JMO, but if Bo stays, I don't think there are any changes on the staff.
Why? It allows Bo to hang himself by his own silly pride.
In the past year, Bo has gotten every single resource he has asked for from the AD, and then some. He's got his coaches, and has had no one forced on him. If recruiting falters, it's on Bo. If player development falters, it's on Bo. If coaches are slacking, it's on Bo. If players are getting in trouble, it's on Bo. This is his program, and his vision of it, completely.
If/When it fails, Bo has no ability to point the finger at anyone. Publicly, he may do it in an attempt to save face. But to those who matter, he won't be able to pull that off.
With the players who we will be losing after the season, and the depth issues we have at quite a few positions, next year is going to be an adventure.
