The only umpiring error that really had an effect on the game was the pathetic centre bounce attempt in the fourth quarter when the Eagles were down by 1 point. Instead of bouncing the ball straight up (or something close to it), it was bounced at right angles directly to Ben Cousins, who gave a quick pass to Lynch for the go ahead goal. West Coast was surging at that point, but up until then, everything had been contested. It spurred West Coast greatly.
That bounce should have been recalled, just as the dud boundary throw in was two weeks ago. Not recalling it was a mistake that should cost that umpire greatly, as it definitely cost the Crows.
A suggestion for a new rule for AFL umpires: if you can't bounce the ball straight, then you lose the right to blow your whistle at all in AFL games.
All that said, West Coast deserved to win. They have beaten the Crows in three straight this year. Adelaide was fucked by luck, particularly with Biglands going down yesterday, but that isn't the Eagles fault.
