Both brett kimmorley and geoff toovey were preferred over johns.
Says it all really.
John had a couple of good games that's it.
He won a couple of spoons too.
Geoff toovey was never preffered over johns. Johns wore number 9 and defended at hooker and packed into the scrums, but played first reciever in attack. He was that good defensively that they could give him a hookers role in defence on top of his halfback duties in attack. Toovey was pretty much just a dummy half. Kimmorley in 7 during 2000 looks silly in hindsight, but he was flavour of the month at the time. You can do the same for Thurston. He was on the bench behind anasta and sherwin for the 2004 gf and gets shifted out of his preferred 7 jumper by cronk for rep games.
Johns 'won the spoon' during 2005, towards the back end of the year when he had an injury effected year, but every year he was on the field the Knights were finalist. Between 2008-2010 Cowboys finished 15-12-15, at the peak of Thurstons powers. In 2008 they were equal last but avoided the spoon on for and against and in 2010 they were the worst team but avoided the spoon because of the storm salary cap scandal.
Both players have lost the same amount of origin series (2), but johns never lost a series/tournament in his time in the Australian jumper.
You can use whatever stat you want to lean the argument in your favour. Both are great players who you'd want in your side in big pressure moments. During the last 5-8 years of his career johns was undisputedly the best player in the comp. During Thurstons times that argument was made for lockyer early on, smith between 09-12, inglis between 12-14 and it's only i the last 2 years that Thurston has been placed in that pedestal above all the others.
The thing that makes me prefer johns, apart from defence, was that he was an innovator. Every few weeks he'd introduce a new way to kick, a new type of pass, a new play etc and it lead to every other half to study the tape and try copy him.
When Thurston won his churchill medal it was behind scott tamou and taumololo up front with morgan by his side, when johns won his churchill medal it was behind Parsons, Perry and Peden with Rudder by his side
