Hey Riggo I wanted to address this because of a past coach tied to his QB.
I think Bill Belichick,,is it only one l? will only last 2-3 years after Brady retires. He's been blessed with 2 top flight QBs in his tenure there, Drew Bledsoe and Brady. So his times there has been carried a lot by 2 guys that were good enough to carry the team on their backs.
Sounds like a guy in Denver who had great success with "Mr. Ed" but soon as the horses mouth retired so did the winning in Denver. Rat Boy has never caught the tempo of winning teams since. He may do better now in Washington cause he does have a possible "great" QB again, but notice he didn't do squat until that happened.
I think either of those guys are merely pedestrian coaches except for the change lightning that struck them at QB.
Seems to me they aren't really great coaches rather 2 guys that were in the right place at the right time. Give me Mike Holmgren who genuinely took players and taught them to play together.(That's my opinion of a coach). Belly Chick and Rat Boy just had to stand by and watch while greatness happened to them from someone else.
That's my 2 cents.
