He does have legit health concerns. He's also still really involved with OSU. He's the assistant AD, teaches a class, also has his own restaurant in the suburbs.
He and Herman have had major issues since Tom got the Texas job. Another rumor was Urban's hold over staff still with OSU had no interest in starting all over somewhere new. OSU will have the #1 or #2 recruiting class in 2021, they will have the #1 in 2022, so OSU will not drop off. Ryan Day isn't Larry Coker.
Def could have come down to staff.
Urban was basically the guy putting himself out there to Texas and he did at least call around asking about a potential staff.
OSU is definitely not falling off.
They own the B1G and are one of the 3-4 current superpowers.
UT was ripe for a guy like Urban though. He'd have run the entire program and been the highest paid coach in any collegiate sport.
He can recruit 5 NFL guys per year just in a 5 hour driving range from Austin.
They'll have a brand new football facility in 2021.
My guess is now UT sucks it up and keep Herman another year.
UT has had a lot of talent but needs an elite QB.
The Southlake kid they lost to OSU would've been that guy.
