I don't remember Collinsworth ever complaining that dez was interfered with, but if he did do you really believe a former WR is going to be objective when it comes to that? Collinsworth is so inane and stupid he's almost unbearable to listen to, but as far as i remember he hasn't compounded that with complaints about interference on Dez.
What, the refs don't call it because they be hatin' too?
When the reality is, Dez simply can't handle physicality directed at him any more than he can handle verbal jousting thrown at him.
