Generally agree but couple of corrections - Football is Division I - they are FCS (formerly I-AA) as opposed to FBS (formerly I-A). Don't think they go FBS as there are many factors stopping it.
They also made Semis in 2009 before losing to eventual champs Villanova and were briefly ranked #1 FCS in 2010 (#2 Seed in that tourney before losing to the triple option team in Georgia Southern).
As for basketball, agree it has generally sucked though gotten better recently. Shaver was able to get the team to a few conference championship games a bunch of years in (5 and 7 years in) which is unheard of for the Tribe so that kept him around until now. Been the bridesmaid 4 of the last 8 years but never won the conference tourney.
All that said, if the Tribe and Gibby can agree for him to come back, the team may have a chance but it seems like the Tribe won't be the cause of firing as they have not done so with any of their coaches.
