I was there. And given I am in the minority regarding the quality of the umpiring, I'm not going to argue with you about it.
Regarding the other point; tanking, I believe any team that puts players in for early surgery is tanking to a degree, so yes, the Eagles were tanking in that regard. But I don't believe that the players on the field or the coaches in the box were trying not to win, which is what the cynics here are saying.
But I'll admit that I may just be hoping, for the sake of the game, that that's the case. I always try to believe that the umpires are doing a good job - at least as far as conforming to the legislation put down by the AFL. And I also hope that no team would ever try to take advantage of a drafting system designed to equalize the competition.
