I disagree Peter. Even it what you say is true, the whole D just flat out stunk. I went to the Pittsburgh game and it was the WORST display of tackling I have ever seen. I think a big part of the problem was Rex' style. Club Rex. He wasn't Coach Ryan, he was Rex their buddy. After he left, last year the guys could once again tackle. that had more to do with than scheme IMHO. That and only 10 men on the field on the biggest play of his tenure.
