I get what the OP is saying,,,but you can't be overly upset about Shaq, Ragland and Dareus since they haven't even played a down yet. Just think when they do come back you're plugging in 1st/2nd round talent to an already good D.
Watkins and Shady? eh, they are fragile. I'm surprised Shady lasted a healthy 6 weeks before tweaking something. Other guys will (and have) stepped up. The only player we really can't afford to lose is Tyrod imo. He doesn't get enough credit for what he does out there to keep plays alive.
