A lot of people complain about whitner because he was drafted so high (not his fault). But then there are other issues with him running his mouth a lot, taking really bad angles (usually one really bad one per a game it felt like), other safties performing better, and more popularity towards Wilson and byrd.
As for lynch, the legal troubles are an issue. One more screw up, and we lose him for an entire season and he is worthless. Whether the legal issues are minor or not doesn't matter. If we lose him for a whole season, then he is just worthless and you can't say otherwise. Then there is the whole thing with lynch not even meeting with gailey yet. And then there is fred jackson, who is just as good or better than him, more dedicated, and more of a fan favorite.
People who hate them might be over-reacting. But there is a lot of saddness that goes with both of them.
