I don't even think UT is in the inner circle now. The inner circle is Michigan, Ohio State, Texas, maybe Georgia and Oregon. Penn State sort of hovering at the edge. Outside of that, it's us, A&M, Florida, LSU, Alabama, Florida State, Clemson, Miami, etc. All in the second ring. All very wealthy, very passionate, but fewer alumni and less centimillionaire types.
That's not mean to slight Tennessee or our fans and their passion. UT just isn't fighting with the same tools those inner circle schools have. No one is.
Ironically, there's a few schools who, if they got their act together, could buy their way into the circle. Virginia is one. An incredible amount of alumni wealth in that school's toolkit. They just don't deign to play in that manner, or at least, they haven't appeared to do so. Also USC, but thankfully college football just isn't big news out there. Miami also has a ton of wealthy alumni, but for whatever reason their attention seems to wander. If the Hurricanes ever do get on track though - look out.
On the basketball side, good luck with Duke. They're also gifted with a number of wealthy alumni, and you only have to buy a handful of players in basketball to have a competitively dominant team. Of course, that's not quite as impactful also. Enough talent in basketball that you can't lock the market down with a dozen purchases. By it's very nature, there'll always be ways to work at the edges. So at least there's that.
