Not really a game of high significance, but Cambo's effort against West Coast in 2002 was probably the best match i saw him play. 36 touches that day together with 4 goals, three which came from tight angles, and one a 55 metre bomb (the longest kick in his career, lol) jsut before the siren to punctuate the win.
Richo's 28 touches, 21 marks and 7 goals against Fitzroy in 1996 was about as dominant a performance from a CHF that I've seen.
