What I see from this...
Anthony Grant build a solid program, and left the program in a decent condition. Shaka took over and built a very strong program. Eventually left for Texas, but left VCU with a presumably strong program still. Will Wade took over, riding the wave that Shaka's success created. He progressively got worse (NCAA 2nd Round in his first year, NCAA 1st Round in his second year), but quickly jumped ship for LSU, leaving behind a bit of a mess for Mike Rhoades, who failed to make any post-season tournament (declining the CBI/CIT, correct?) in his first year.
So what you're saying is the drop off occurs when the previous coach leaves the program a bit of a mess? Thank you for drawing that comparison to the '17-18 Akron program.
Also, thank you for bringing up VCU as a comparison. One of Dambrot's assistants left to coach VCU, and made his own luck/success at VCU, taking that school to the next level and into the A10. Did the CAA win those NCAA tournament games? Nope. Did the CAA beat those high-caliber schools? Nope. Shaka and VCU did. They didn't need the CAA's help.
And that's why I'm optimistic about next year and the future in general. I think we have a guy at the helm of our basketball program that isn't going to look for others to help him become successful. He's going to build the success on his own.
