By Kyle, you mean Kyle Williams, I assume? Maybe they stunted more under Jim Schwartz or Wrex.
I don't recall them doing much stunting at all last year. Even in season's past, Leslie Frazier is not the type to be aggressive up front. I'm wondering if that would be any different if McD, himself, was the DC. I don't recall what Carolina did as far as the line goes.
Anyway, Leslie is fairly conservative regarding what he does with the line.
