If you think he's good at coverage, fine. I just don't like it when people just give him a pass on it because "That's not what he does". No other player on the team gets his mistakes glossed over like that that. I've never heard anyone say "Don't blame Flozell for giving up sacks, everyone knows his strength is run blocking. Its really unfair that he's asked to do both." Especially for a Top 10 pick. If we drafted a defensive tackle with a Top 10 pick, I would hope that he could both collapse the pocket and stuff the run.
I perfectly understand that he's at his best playing in the box, but people are living in fantasy land if they think the Cowboys can afford to go with a 3 DB, 5 LB lineup all season. There will be times when Dallas needs their strong safety to be a defensive back.
