Hopefully they can keep him for another year but it’s a very realistic possibility that he walks. He will definitely be interviewed. Can they offer to give him a raise to try and keep him if it comes down to it?
Continuity under a competent OC (or offensive HC) seems important to develop talented young QBs until they can reach their potential. Past a few years they’re vets and can stand on their own.
If they need to replace him, it seems like it would be a good idea to try and have some continuity with the Shanny tree given familiarity. But who fits the bill?
If he gets offered a HC job he’ll take it. Those opportunities are never guaranteed to come again, and obviously the money is ridiculous.
That said, I don’t think he’ll get an offer. He may get interviewed, but I think he’s still in prove-it mode for most.
But, it only takes one desperate owner to ruin everything…
