Many, many coaches who used to coach for Nick Saban have been hired away by other teams. I used to think that our coaches did not leave Clemson out of loyalty to Dabo and the school. Now I am not so sure. Perhaps some of them are just not attractive candidates to other schools.
Nobody wants TE. He's not an offensive genius or a CEO HC. He may get a shot at a FCS school or low level FBS but he isn't in the running for a Big 10/SEC job.
And the rest of the offensive staff are all ex Clemson people who are too green. Dabo messed up surrounding himself by yes men. Not the first time this has happened but often occurs with someone who rose to the top from the bottom. They don't learn how to stay at the top. Just to get there.
