When you're as consistently bad as we've been, it's not bad luck. We're doing it wrong. You're correct.
I think you misunderstand the issue. A lot of folks have posted stuff like you just did over the years. Uncertainty in any instances is a totally separate topic from consistently bad choices that form a pattern. The NFL may get it wrong 50% of the time. If so, that's considered average, and an NFL team that gets it wrong 60% of the time is doing poorly, while an NFL team that gets it right 60% of the time is doing much better than average. The under-performing staff can expect to get fired at some point. The out-performing staff is likely winning on the field, also. Even the best teams may get it wrong a lot, because it's an uncertainty business. But getting it right more often than the average competitors is how you stay better than them.
At UM, the pattern shows we've evaluated really poorly at WR, IMO. Consistently poor outcomes in an area rich in WR prospects.
As for whether you should care what other people's opinions are, totally up to you, but not sure why you're posting here if you think the opinions expressed here don't matter.
