Yep, pretty much this. Programs like FSU (Leonard Hamilton), Miami (Larranaga), and Virginia Tech (Buzz Williams) were all pretty much after thought programs. Buzz had VT in the NIT in year 2, NCAA's in year 3 and they made 5 straight tournaments (including a S16), despite him leaving after 2019. VT was in MUCH worse shape than we were when we hired Ben. Miami had one tournament victory, in the previous 7 years prior to Larranaga being hired (sound familiar) FSU had made one tournament in the 9 years prior to Hamilton. Hamilton's had the best run at FSU dating back to the 70's.
Houston was shit for about 3 decades prior to hiring Kelvin. And it should be noted when he was hired they were in the AAC. Hell you can even add NW and Collins to this list. They haven't reached the heights of the others, but going to 3 tournaments in an 8 year span when having never gone before is pretty good.
