Maybe I'm a softie, but given that Pruitt is a first time head coach taking over a program after an embarrassing coaching search that went 4-8 (0-8) the previous season and hasn't finished in the top 15 since 2007, the #12 class overall isn't that bad. These kids he's trying to convince to come to Tennessee have never personally seen a Tennessee program that was relevant. The 2019 class was still 7th in the SEC, but it would have been 2nd in the ACC, 3rd in the Big 12, 2nd in the Big Ten, and 2nd in the Pac 12. It was in the same ballpark as Florida and Clemson, was basically equivalent to Auburn (0.01 points less than Auburn's composite score), and was better than Penn St, Ohio St, and Notre Dame (who was coming off a CFP appearance). All things considered, it wasn't bad at all. Does it need to be even better eventually? Probably.
Personally, I think overperformance on the field needs to come first, then that leads to better recruiting, then that leads to even more winning. That's how Dabo did it at Clemson, which is probably the most relevant comparison I can think of. Clemson did not start recruiting at a consistently elite level until Dabo started appearing in CFPs - just look at the 247 Composite, and he still doesn't pull classes rated as highly as Alabama's, Georgia's, or LSU's.
