Alani Fua's made many great plays, and has often followed them up with something that extends the opponents drive.
Mitch has had some penalties (the late hit vs. UConn for instance) and comments in the media that indicate a little attitude.
Bronco prefers having aggression and needing to tone it down, vs. having to coach it into players.
We're lucky to have them both probably, but this hasn't been a "mistake free" football team for...years.
