Definitely one of the downsides to running a 4-4 defense. You put a lot of pressure on either your outside linebackers to run with receivers or you put your CBs or Safety in pretty difficult situations. It hasn't been too much of a detriment over the years though, as you said.You could say that about the pass defense for the last 30 years or so. Partly by design I think, hard to argue with the overall results
