I don't understand how people say this and truly believe it. Welker is basically the same size and has taken some huge licks. But he hasn't missed a game in 4 years! Tavon was never injury-prone and his shiftiness will help him from taking big hits every time. How come nobody completely writes off Justin Hunter because of injury? He is frail and actually has an injury history.
If your going to knock Austin please find something about his game you don't like or a personnel argument. You're better than that rumblers.
