I'll break this down piece by piece.
For me, personally? Correct. You cannot convince me the quality of life for a $2.2 million salary per year is that much better than $1.8 million - $2 million a year. Those are the reported "rumored" numbers we've heard. What could Tony buy with $2.2 million per year that he can't buy for $2 million per year? Or $1.8 million....the difference in salary there is negligible in the grand scheme of things.
Prestige is overrated. How prestigious is Tennessee football? It used to be incredibly prestigious, and look at our dumpster fire of a program now. It seems the prestige has worn off a bit. Vanderbilt wasn't a prestigious baseball program until about 7-9 years ago, now it's a household name. You can build something at arguably any Power 5 conference if you're the right person for the job.
As far as the resources to succeed comment, LSU has better facilities at this moment in time, but TN is going to commit substantial funding this off-season to close the gap. TV is 42. If he keeps winning, the gap will only narrow even more and quickly. We're not a poor program.
