As of right now they are still keeping 4 of 5 starters off of an 'improving' team. Then they'll add Asuma and whoever else coming in from the transfer portal.
The buyout will decrease, and the optics will be better if Ben is given another year. Fire him now and there would be some local media outrage saying he wasn't given enough of a chance, and maybe some potential new coaches would also feel that way.
Obviously I don't think Ben is the right coach, it has been obvious for awhile, and we continue to waste our time as long as he's in charge.
But after 4 years if you can't make the NCAA tournament, and have the worst record of any previous head coach that was given 4 years, there will be very little argument by anyone to make a change after next season. Plus the 4 starters that are currently returning will likely all be gone after next season.
