Correct. I'm also willing to stick with Sark for the long term because his history as an OC & Head Coach in CFB, shows he always updates & evolves his offense with times.
Sark has never won consistently in college at his previous two stops
a leopard doesn’t change his stripes
Sark's best season at UW was his last season in 2013, when they stopped running a pro-style offense & went all in running a modern spread offense. His success that season is what lead him to being hired as USC's head coach. So he did turn around UW as a program, which is what allowed Chris Petersen to come in next season & start winning immediately.
Sark was only USC's head coach for like 1.5 seasons before he was fired for his drinking problem, winning 9 games in his 1st season, so we don't know what he would've done at USC if he wasn't an alcoholic.
