Exactly. Dez should be doubled no matter where he is period end of story. If you want to put Prince on Austin to "take him out", that is okay, but then Dez needs to be doubled by a CB AND Rolle. Not one on one every single play with a S Rolle.
That is terrible coaching. The Cowboys were targeting Rolle, no doubt. 4 or 5 passes were completed on him that last drive. They found who he was on and made sure they got the ball.
Bottom line is they had a 3rd and 5, and a 3rd and 7, and neither time the D got a stop. Neither time the D blitzed. Same old Giants D in crunch time. Is what it is. Big picture it was a good L IMO, just stinks it was against Dallas. That is what angers me most.
And if Coughlin doesn't fire both coordinators, he should be fired also as was said above. Both Fewell and Killdrive must go.
