This isn’t easy for me but I’m going to try give an objective opinion. The only TN sport I know well is football, and I think TN football is in really good shape. I’m not predicting you’re about to win a natty, but I am saying it wouldn’t be terribly surprising if it happened before Nico leaves.
Obviously, this is if Nico develops as expected. I think he will be very good eventually in CJH’s offense. Two years ago proved what your offense is capable of with a very good QB, and I think it’s likely that Nico will lead a team with more talent than the 22 team before he leaves.
If the offense can get back to that level and have a stronger defense, TN will be very tough to beat. The last two seasons were really good seasons. And if Nico shines, it will be easier to attract top level transfers. Unfortunately it will also take money in most cases, but TN should be fine on that front I would think.
It’s unlikely that you catch up that quickly with the talent levels of Bama, GA, or Ohio State, but I don’t think you have to be all the way there to be competitive with them. It will be tough, but like I said, I wouldn’t be surprised. In truth I’d be a little sad, but not terribly surprised.
