Coaches typically aren't able to double dip from being a commentator and from their coaching gig. It was the case with Doc and publicly with Rex Ryan a few years ago.
Rex’s contract had a previously unknown offset included.

Offset language is rather common in these type of contracts. It's why I kept telling posters last year that Key wasn't going to be able to double dip from ESPN and FS1 eventhough that one tweet said otherwise.
The only instance I can't think that it was included was with Jimbo Fisher.
