Not really.
Outside of FAU tell me where he improved the situation he left?
Raiders...Nope (5-15)
Tennessee ... Nope (7-6) and violation issues
USC... nope and nope 8-5, 10-2, 7-6, 3-2 fired
As an OC yeah he's decent but his track record has been shit and you would rather have him over Gus, maybe all things being equal when Gus was hired perhaps I would have been on board, but not with the current data points we have.
