Honestly I would say common sense unless we show some promise AND have some serious talent waiting in the wings (aka Carton)
If we *suck* next year, he is obviously gone.
But say this is an NIT team -- somehow -- and he has seniors Bolton, Conditt, and Johnson, the four sophomores taking the freshman-sophomore leap, a fresh recruiting class of high school and prep school players (way more Prohm's strength as a recruiter), and a guy or two coming off a RS as reinforcements for the 2021-2022 season.
That is, the roster is set to peak and/or redeem itself next year.
And if it won't work then, it will never work.
Does he get another year and one last chance to prove it or no...?
