Johns v Thurston a statistical attempt

On Tuesday Fox Sports released an article attempting to compare Andrew Johns and Johnathan Thurston, by the numbers. The article only compared games, points, awards, titles, etc. In my opinion they could have done a better job. This article will attempt to go a little further.

Comparing these to great Halfbacks is no easy task, as I am not a statistician and do not have access to NRL stats databases. The stats I have managed to find on Andrew Johns are incomplete. The reason for this is the NRL did not start collecting detailed statistics (Line Breaks, Offloads, etc.) until 1998 and in the seasons that followed they increased in detail (Try Assists, Line Break Assists, etc.). Another issue with this comparison is the different stats providers, for example: all the stats I have for Andrew Johns were recorded by the NRL’s old stats provider Sports Data and the stats I have on Johnathan Thurston were recorded by Fox Sports. The reason I have not used Sports Data stats for JT is they are only available up till 2007. This is an issue because different stats providers have been shown to have differences in their records, for example: for the 2007 season Sports Data recorded 31 try assists and 19 offloads for Johnathan Thurston, while Fox Sports recorded 30 and 16 respectively. The issues mentioned above illuminates that this is a flawed attempt to compare the incomparable.

They have each played 249 first grade games; Joey won 61.8% of games, including 2 premierships for Newcastle, while JT has won 53.8% of games across 2 clubs including 1 premiership. JT has taken part in 8 winning series for Queensland; winning 63.3% of games compared to Joey’s 5 series wins for NSW at 56.5%. As a side note: 16 of Joey’s 23 Origin appearances were at Halfback, while the other 7 were played at Hooker or off the bench. Joey won 87% of games for Australia, with 2 World Cup victories; while JT has won 93.5% of games for Australia with 1 World Cup victory.

They are equal on top with 3 Dally M Medals a piece, in addition they have taken out 2 Golden Boots. JT has the edge on Dally M positional awards with 6 (3 at Halfback and 3 at 5-8) compared to Joeys 4 at Halfback. Joey claimed a Clive Churchill Medal in 2001, the only major award JT is without.

To this point we have covered all the basic stats that everyone already knows; we will now delve into the nitty gritty, starting with their attacking game.

JT V Joey[Andrew Johns Stats sourced from Sports Data’s NRLstats.com; Johnathan Thurston Stats Sourced from Fox Sports.]

As discussed above the stats I found on Andrew Johns were incomplete, which makes this comparison unfair for both players. We of course have a complete record of Joey’s tries; scoring 80 from his 249 games compared to JT who has crossed the line 81 times from 249 games, a per game strike rate of 0.32 and 0.33 respectively. I only have try assist stats for 147 of Joey’s appearances, where he managed 166 at a strike rate of 1.13 per game. JT has assisted in 259 tries at a strike rate of 1.04 per game. Joey broke the line 107 times in the 173 games that were recorded, a strike rate of 0.62 per game; compared to 149 line breaks made by JT at 0.60 per game. Line Break Assists is the smallest sample I have on Johns as they were only recorded for 81 of his 249 appearances. In that period Joey assisted in 105 line breaks at a rate of 1.30 per game. JT has assisted 268 line breaks at a rate of 1.08 per game. Joey dominated when it came to forty twenties; kicking 16 from the 147 games recorded at 0.11 per game; compared to JT who has only managed 6 from 243 games (couldn’t find stats on a few finals games) at 0.02 per game.

Joey produced 338 offloads in the 173 games that they were recorded at 1.95 per game; compared to JT who has to date produced 232 offloads at 0.93 per game. Joey averaged 60.78 metres per game in the 147 that were recorded; compared to JT who has averaged 63.50 across his career. It’s fair to say that if we had complete stats on Joey’s career his per game averages would slide back towards JT’s numbers; however, how much is unclear as we are missing stats on years where he won a Premiership, a Dally M and a Halfback of the year award.

 Johns DefenceThurston Defence[Andrew Johns stats sourced from Sports Data from 173 of 249 games, Johnathan Thurston’s stats sourced from Fox Sports across 249 games = % (total tackles/total attempts displayed as percentage)]

I found Defensive stats for 173 of Joey’s games where he averaged 14.61 tackles per game, missing 2.03 per game. JT‘s has averaged 14.70 tackles per game across his career averaging 3.50 misses. Fox Sports has JT’s effectiveness in defence at 75%; this must include ineffective tackles, which I could not find figures for. To be fair to JT I used the same simple formula that was used for Joey (total tackles made divided by total tackles attempted times 100). Using this simple method Joey made 88% of all tackles attempted compared to JT who has been 81% successful.

When it comes to errors and penalties the stats I found indicate that JT is slightly less disciplined. In the 173 games that errors were recorded, Joey made 213 at 1.23 per game, compared to JT who has made 396 errors at 1.59 per game. Penalties were only recorded for 81 of Joey’s games where he conceded 44 at 0.54 per game, compare to JT who has conceded 156 at 0.63 per game. In addition JT has also been sin binned on 4 occasions. I am not sure if Joey has ever been sent to the bin.

Highlighted red text means the data is incomplete. * Numbers have been derived from per game averages times the total games, therefore the figure will not be totally accurate.]

Numbers won’t settle the debate as people either love or hate these two players. From my perspective it has been fantastic watching these two magicians dominate over the years.

Who will replace Jarryd Hayne?

Speculation over who will replace Jarryd Hayne in the Blues line up started the moment he made the decision to switch to the NFL. Early popular opinion had Penrith young gun Matt Moylan in the hot seat. Last week NSW coach Laurie Daley named Josh Dugan, Brett Stewart & Matt Moylan as the main contenders for the Blues custodian role. With only 5 rounds down and 5 to go before the team is announced for the May 27 opener, debate is sure to heat up.

The purpose of this article is to compare purely with statistics Jarryd Hayne’s form after the first 5 rounds in 2014, with: The Blues main Fullback contenders, longshots and the likely Maroon fullbacks. This article will only look at some key areas based on simple statistics that are readily available to the public. It in no way tells the whole story, but should provide some good early season talking points.

 Attack APPG Hayne[Attacking Plays Per Game (APPG) = the sum of: Tries, Try Assists, Line Breaks, Line Break Assists, Forced Drop Outs & Forty Twenties; divided by games played. Stats sourced from Fox Sports.]

Matt Moylan has been the most potent attacking Fullback on our list after 5 rounds, averaging 3.6 attacking plays; which is slightly higher than Hayne at the same time last year who averaged 3.4. Moylan comfortably leads this list in try and line break assists with 7 and 6 respectively. James Tedesco has recorded the most tries with 5 and Brett Morris who has been ruled out of Origin this year with a hamstring injury, leads line breaks with 7. Will Hopoate in his new role, has been the least potent Fullback in attack; averaging only 0.4 attacking plays. As a matter of perspective, in form Fullbacks average over 2 attacking play per game and the best average 3 plus. For example Hayne, Slater & Inglis averaged 4.2, 3.0 & 2.4 respectively, during the 2014 regular season.

Run Metres

Run Metres Hayne[Total run metres divided by games played. Stats sourced from Fox Sports.]

What Will Hopoate lacks in attack he makes up for in work ethic; averaging 162 metre per game; the most of all Fullbacks in this list. Hopoate is closely followed by Jack Wighton and Brett Morris with 157 and 153 metres respectively. Hayne averaged 135 at the same time last year; however, he finished the season averaging 178. Brett Stewart has only managed 69 metres per game so far in 2015; 20 fewer than his 2014 average. Stewart is managing less metres then journeyman Kurt Gidley who has returned to the custodian role.

Second Phase

SPPG Hayne[Second Phase Per Game (SPPG) = sum of: Offloads & Tackle Busts divided by games played. Stats sourced from Fox Sports.]

Brett Morris and James Tedesco lead the way in second phase plays so far in 2015 with 7.3 and 6.6 per game respectively. Tedesco has broken the most tackles with 30 and Morris has the most offloads at 6. Josh Dugan and Lachlan Coote have also proved difficult to tackle; averaging 5 a piece. Brett Stewart sits at the bottom in this area; a direct reflection of his run metres. He has only managed 1.5 per game; with a total of 3 tackle busts and 3 offloads. Hayne averaged 6.2 per game after 5 rounds; finishing the season averaging over 7. Greg Inglis and Billy Slater are both down in these areas compared to last year; both averaged close to 5 at the end of the 2014 regular season.

Defence

Defence Hayne[Total tackles divided by attempted tackles, displayed as percentage. Stats sourced from Fox Sports.]

Kurt Gidley at 98% effective in defence is technically the best defensive Fullback so far in 2015; however, his numbers have been greatly inflated, due to not exclusively playing Fullback. Gidley has already made more tackles then most fullbacks over the course of the 2014 season. For this reason we will exclude him. Josh Dugan at 92% and Will Hopoate at 91% are the best ‘true’ defensive Fullbacks in this list. Greg Inglis at 78% is well down on last year where he defended at 90%; the best of all any Fullback. Inglis only needs to miss more tackle to equal last year’s total. Matt Moylan is the worst of the contenders at 69% effective, down from 80% in 2014. Hayne only managed to be 71% effective throughout the 2014 season which was well down on his career average of 80%. This statistic provides the least insight in my opinion for Fullbacks, because they make so few tackles. It struggles to be truly representative of their defensive ability.

Errors and Penalties

EPPG Hayne[Errors & Penalties Per Game = the sum of: Errors & Penalties, divided by games played. Stats sourced from Sports Mate League Live.]

Josh Dugan and Jack Wighton have been the least disciplined in 2015 averaging 2.3 errors and penalties. Moylan, Tedesco and Wighton have each produced 8 errors; Dugan, Moylan and Hopoate have each conceded 2 penalties. Hayne averaged 1.2 at this point last season, but finished the season averaging 2.0. Greg Inglis continues to be one of the most disciplined fullbacks; only producing 0.4 per errors & penalties per game; slightly better than 2014 where he averaged 0.71.

The season is young and the debate will continue to rage; the potentials mentioned above still have plenty of time to step up, and show the selectors they have what it takes to succeed in Rugby League’s toughest contest. As I am only a fan of stats and not a statistician, it is hard to know what, if anything these simple comparisons mean; however, it is always nice to throw some numbers around in a debate.
