I know this is meant to be critical, but I actually think this is a very sensible way for fans to behave. If an organization gets good at determining if a player will be any good, and churns liberally, then it's how you add talent and not waste time lingering on moves that don't pan out. What's wrong with that? Turn over stones, if they don't work for you, release them and move on. If you get better at finding promising stones in the first place, your roster gets better, and you don't give yourself an ulcer proclaiming every move a likely failure in advance.
Many, many personnel moves in the NFL are going to be failures. Complaining about that fact is like complaining about gravity: it's just they way it works. Dropping apples and yelling "I knew it!" doesn't impress anybody. I can't speak for anyone else, but I know I've never been impressed by the predictive acumen of any poster who just doesn't like any move the team makes and then points to his or here track record of those players no longer being on the roster.
