If Jimbo stayed, they would play through next season likely losing 4 games and end up with a team with poor morale, a dead coach walking, and having players sit out their administration’s Super Bowl against Texas.
Now, while yes they have a built in excuse (1st year head coach) they also can tell them (similar to what UH told coach redbull) you can go 1-11 next year as long as that 1 win is against Texas.
The next coach will design their offensive and defensive identity around creating the optimal base scheme that will most effective against Texas. Spring ball, fall camp, and every bye week will be focused on Texas. The coaches will watch and analyze film on Texas all season long and will have the team prepared to play spoiler.
Their best chance at beating us is letting the mercenary players go back to New Jersey or Tennessee, and build a roster full of true believers in a coach (like Traylor, who imo would be the worst hire for us since he can leverage his Wast Texas roots and THSFB coaching connections, but aggy is hopefully too proud to go after a UTSA coach) who are in it for the long haul. They could only do this with a new coach with proper expectations set in advance of hiring. No way you could do that with a year seven Jimbo.
