Let's see:
-The guy has been fired from several different positions after short periods of time
-He's coached a million different places
-Likely was considered for this position because Golden knew him from Golden's illustrious tenure at Temple, where this guy coached the greatest defensive lineman in the history of the game, Muhammed Wilkerson
The job we hired him away from was FIU, one of the biggest dumpster fires in all of the NCAA
-Our defensive line has grossly underperformed during Golden's time here, largely because of the scheme, but even with the terrible scheme, our guys have clearly not played well, and could really use a good defensive line coach
Oh yeah, and nothing our coach has done in his four years here, from coaching decisions, game strategy, recruiting, etc, has proven to be successful.
So, yeah, I think I'm going to assume that this is a bad hire, that we have again chosen to stick with what we know rather than go after something different, and that this is likely to make no difference in the results on the field with our current head coach and defensive coordinator.
