Wayne Carey was a champion but wasn't he pretty quiet in the Grand finals he played? Other big games he might have gone well but the grand finals are the biggest games of all.
Carey had servicable Grand Finals, but kicked poorly for goal in them.
Big game players are more than Grand Final players and Carey 1994 finals series is one of the greatest finals efforts in the history of the game.
1994 v Hawthorn: 32 disposals, 10 marks 4 goals, 4 behinds
v Geelong: 24, 14, 6.4
1995 v Richmond: 22, 9, 5.4
1996 v Brisbane: 24, 14, 3.2
v Geelong: 23, 10, 3.2
v Sydney: 22, 9, 1.3
1997 v Geelong: 23, 10, 7.0
1998 v Essendon: 24, 8, 5.6
1999 v Port: 24, 11, 6.2
That's 9 pretty good finals games.
There would be better, but not too many better.
