I find it hard to believe that a coach at the NFL level cant come in with the existing personnel along with a couple of changes and run a 4-3 or 3-4 and be 100x better.
The current D scheme is the worst I've ever seen.
Probably not. But I think its the duo of BQ and MP. The DEF scheme is awful. How many more guys do they need to make it successful? I would think a new coach could come in, install a 4-3 with the personnel they have and be ok.
