As other have said, hopefully Sensabaugh can land on his feet. He's a great person. And as bad as he was here, it was not for lack of effort. At times his coverage was actually quite good but he could just never make the play despite his strong positioning (see: Dez Bryant TD). He has some NFL experience. I hope another team gives him a chance and he excels. I think he can be better than what he showed as a Ram, but it wasn't going to happen here.
I particularly like this move because it shows Fisher admitting a mistake in very short order. That's both surprising and welcome. We never should have signed Sensabaugh to being with. Better CBs were available in the same price range.
The promotion of Fox indeed seems to signal we might have troubles with the health of our DEs. Quinn came back and played last week after getting hurt, and his injury was referred to as a "stinger". Even if he misses time from the shoulder I don't think it will be a big deal. Ankle injuries, however, can be a real issue. Hopefully this doesn't mean starter William Hayes is in worse shape than first thought...
