I think he'll go if he gets the right offer. He got to coach his sons and now he can make the jump to the NFL, where they will be.
Not sure if you have been keeping up with his comments over the last year but he really doesn't think he would enjoy coaching in the NFL.
He has said many times that he much prefers coaching college players over NFL players and that's why I have said I think the only way he goes to the NFL, at least any time soon, would be if he could coach his son, Shadeur.
The best way to do that would be to wait a year, let a team draft him and see how that team does.
If they do well, then Deion remains a college coach. If Shadeur's NFL team does poorly then he might consider moving to the NFL to coach his son's team.
Given Deion's attraction to the spotlight throughout his career, if he was not going to coach his son's team, I think the Cowboys would be at the top of his NFL wish list to coach.
The fact that he has basically said he's happy at Colorado after taking with Jerry further confirms that he's happy being a college coach and the only likely way that would change would be if he could coach his son.
Even then, I think he would only do it if Shadeur's team is not doing well.
