Lots of good stuff on

The short of it is Gus was 'forced' on Nutt to both improve the offense and get the high school guys from Gus' team. Nutt said "ok" to get the players, then essentially shut Gus down.
Nutt's offense was the RBs... there was not much influence from Gus by most accounts. So, he left and I can't blame him.
I hate Houston Nutt.
