Bronco is a Dick LeBeau disciple on D. We run the same 3-4 with similar blitz and pressures.

Pittsburgh is struggling due to an inability to consistently pressure the QB. This scheme is entirely dependent on it.

They just talked about the great edge rushers the Steelers gave had over the years and how they jack that guy right now.
The discussion rang so true with respect to BYU. Lack of pressure is a killer this year. Sacks are down. Tackles for loss are down. QB hurries and hits are down. The scheme works exceptionally well when that element is present, and not well when it isn't.

BYU needs to figure out which guys can create that pressure. And fast.
