You totally missed the point of that statement. It wasn't saying Hall was Heppler's equal, it was saying Heppler is the only men's coach at GT that comes close to what Hall is doing.
Yes, I get we're all disappointed, especially with the talent GT has been getting. Postseason results (including ACC tournaments as well as NCAAs) should have been more fruitful. This situation reminds me a LOT of Herb Sendek's time as NC State's basketball coach. For his last 5 years, he made the NCAA tournament only getting past the second round once. NC State fans and donors pushed him out. After Sendek left, they were able to go to the Sweet 16 gain twice under Mark Gottfried, and Gottfried had a run of 5 years with NCAA tournaments (never getting past the second round outside of those Sweet 16 appearances), but success has been few and far between the past 17 years Sendek has been gone.
I'm not saying GT can't do better than Hall, I'm just saying be careful what you ask for.
