season, much less mid-game, for anything besides injury? The only instance I can think of is replacing a senior Tanner Mangum who due to injury was clearly a shell of his former self, with a freshman Zach Wilson, who was clearly the better QB even back in fall camp, but needed to get the hang of the playbook first. That move was a combination of playing the better player who was also younger to build towards the future.
Gerry Bohanon never clearly separated himself from Jake in fall camp, and Jake has one more year of eligibility, so neither of those factors apply here.
