Tom Herman in 2017 and Scott Frost in 2018 were the can't-miss G6 coaches destined for bigger things. Lot bumpier transition than most expected. Herman didn't last long at UT and it's not looking good for Frost.
When the best you can recruit are 3-star players, it’s actually easier for a coach to impose his culture on a team.
But when you move up to the big boys, there is a lot of pressure to pull in the 4 and 5 star players, regardless of whether they are a good fit for your team.
