True, but it's not the break out that you said was coming. The Collingwood games happen maybe 2-3 times a year. Sure, anyone playing for a top 4 team is going to be a contributor but I think it's been another underwhelming season thus far despite all the Brisbane fans coming out in droves post the Collingwood game.
Let's sum it up post finals, that is what will matter most. If you isolate Rayner's games forward, 17 goals + assists in about 7 matches and 15 Sherrins and over 6 contested is pretty tidy.
