I don't think Dabo wants to merely "survive". He has tasted winning in a much bigger way than the Clemson fan base has and he probably isn't going to hang around and be "almost great". I think it depends a lot on how strongly he feels about the portal, NIL and the upcoming direct paying of players by the schools. He has always been pretty vocal about being opposed to all of those things. I guess we'll see how committed to his values he really is.
One thing is certain; unless he has blown money like no one in history ever has, he isn't going to stay at the job because he needs the paycheck. It wouldn't surprise me much if he walked away in the next year or so.
