Then they should pay him more if they value him. That's a strange move.I believe they promoted to Crennel the front office or assistant HC so that could promote Verifable to DC to keep from losing him to another team who was wanting to promote him.IMHO i think the Texans thought he was to good of a coach to lose.
If he is about to hit 70, it's definitely time to retire.I believe Crennel was close to retiring, and is likely done next year or so. It's likely not a step down position, but a less active role for a guy that's close to calling it a career. Believe he's about to hit 70 years old. And it was either promote Vrabel or lose him, so they probably called them in and had a unanimous agreement.
