The position Barwin plays for Phillips does not call for a player that makes 44 tackles & 3 sacks. Watt's productivity should allow Barwin to get free and dominate the QB. He is not being double teamed.
Quin playing behind our corners is in a prime position. An article in Houston paper today by David Barron asks if Joseph can cover Bengals' AJ Green. He quotes former NFL all pro safety Darren Sharper "JJ is not good when he's on an island."
If Barwin leaves we do have two starters in Reed and Mercilus. If Quin leaves we are in wee bit of consternation with no one behind him.
