Actually, it is true that he has more trouble with athletic DEs, then power DEs, but other then 2011, he has done as good or better job against athletic DEs as most of the other LTs in the NFL, but unlike other LT, using a power move on Jake is going to almost always get you nowhere near the QB.....in fact Jake loves it when a DE tries to bull-rush him.
Don't get me wrong, he WAS elite for a few years, but he's a shell of his former self.
And to be honest, I can definitely see both sides of the coin here. You let him go and there's potential for his injury concerns to be non-exsistant. You keep him and there's potential for him to continually to be an injury problem. So if you 'simply cant understand....', then you are blind to other possibilities. If your opinion differs, fine. But don't act like it's an outrageous notion that Long has become injury prone. You dont know any more than I do. So stop acting like your opinion is the only one that could possibly be right.
