Leach is very frustrating because he could be great today like he was great 20 years ago but he doesn't care at all to adjust his offense. Briles and Riley took his passing concepts and married it to a power spread running game and their offenses became dynamic. We also know that going to traditional splits helps the running game but doesn't hurt the passing game. Leach has no interest in doing either and that level of hubris/stubborness is mindblowing.
