I just think a reasonable amount of concession has to be made from fans - that at minimum they can't have the same amount of information as a team. It's a hunch or a gut feeling on both sides but I give the benefit of the doubt to the team because of information.
For example I watch a good amount of college basketball and my wife watches none. She could easily beat me in filling out an NCAA bracket. However that doesn't mean she evaluates better than me, she got lucky. It may be that she just picked the winner and got more points in the end.
So of course a fan can be right and a team wrong. It doesn't mean they're stupid or unable to do the job. They took a shot on Allen - let's see if they got lucky.
