He didn't take his foot off the gas, he's a moron.Because he went 11-11 in the 2 seasons after winning it all and by most accounts completely took his foot off the gas after winning the title in 2019, plus hit on a booster's wife at a gas station.
If anything, the LSU admin kind of went easy on him. There was off-field turmoil at the time too related to the Derrius Guice allegations and other Title IX issues. They probably just didn't want all that aired publicly so they paid him the money to go away.
He went 11-11 because he lost Joe Brady on offense and Dave Aranda on defense and didn't know how to correctly replace them.
