Uconn is in a tough spot. It's not easy to recruit top players to a program that is currently stuck in the G5. Especially when the coaches promote a generally unappealing brand of football. Uconn needs to recruit players from the same pool as Cuse, Temple, RU, BC, but tries to do it with one arm tied behind its back.
While I find Diaco's Personality fascinating, I was not a fan of Uconn hiring him when they initially did. After The Pasqualoni Debacle your program desperately needed leadership and experience at the top. Not only that, they needed a jolt of excitement to engage a fan base weary of losing. What they got was a former blue collar linebacker who coaches like he believes Hayden Fry's Offensive game plans at Iowa were far too progressive for this team. He might say all the right things, run a generally clean program, and develop good kids, but his brand of football as a product is bad entertainment. There is a referendum every week on his product when you see the emptiness of the stadium.
I'm not sure that financially the AD could absorb letting Bob go this year, but on the other hand the damage to the program another 4-5 win season could do might outweigh any check they have to write. If they do pull the trigger they better be looking at offensive guys with former HC experience. I know people don't like the idea of guys with questionable pasts, but considering the position Uconn finds itself in they may need to swallow hard.
If you hire this kind of coach, you do so with the knowledge that he will be on an incredibly short leash. Guys like Briles and Sark come to mind immediately. Both are likely chomping at the bit to redeem themselves and would likely seriously entertain the position. Possibly wait for the firing season to see if any offensive guys like Rich Rod, Helfrich, or Dan Mullen get cut loose. If not look any of these guy then you look for an offensive innovator at The CUSA/MAC/Sunbelt Level. UConn is at a critical junction in its history, They are fighting for the relevance of its program. 41-3 at 2-5 ECU should not be good enough for anyone.
