I'm not going to freak out but I'm not going to pretend like this isn't cause for pause. The fact that Michael Thomas is still not 100% is crazy to me. It seems like he's been gone for 5 years.
As far as Dav goes, he's always going to be dealing with some sort of injury or malady. He's just one of those players. I call them Can't Get Right guys. Their bodies can't handle football. At the other end of the spectrum you have guys like Cam Jordan and Will Smith who bang out season after season relatively healthy.
