I believe you could categorize Musgrave as a direct disciple of Shanahan. But I will note this that I recall people not being too favorable with his ability to run an offense in Jacksonville.
Also, the other vacant coaching position may be filled soon as well. I just read this, and it perked my interest. Pure speculation on my part, but maybe...
In regard to coaching vacancies, scout.com was told early Tuesday that former New York Jets defensive coordinator Donnie Henderson would be hired in the same capacity with the Lions. scout.com was also informed that Jets' offensive line coach Doug Marone had secured a job with another team and veteran offensive line coach Tony Wise (Panthers, Dolphins) would likely replace him.
The Jets used a zone-blocking system last year under Heimerdinger and Marone, so would this be a possible hire for the Falcons?
As for Gibbs leaving for Houston, it was definitely a possibility when I first heard Kubiak would be getting the job there. But I figured that if Gibbs wanted to go full-time again, he'd stick here in Atlanta. Houston would definitely be a challenge for him, but I don't think he's at the point in his career where he needs another feather in his cap. 99% of the world already considers him the best OL coach in the league. Maybe he's trying to be the first position coach to enter the Hall of Fame. If he can make Houston's OL into a good unit, I'd vote for him if I could.
