Plus, people are comparing the two coaches at different points in their careers.
Belichick had his superstar all-time QB early in his career, whereas Reid finally got his when he was 60+ years old.
I really hope Reid continues to coach until he's 71 or 72. Then let's compare Reid at 72 to Belichick at 72, where he is now.
IF Reid's still active until age 72 he will hold every single statistical advantage over Belichick except (maybe) SB rings. Plus he has a pretty successful coaching tree of guys who went on to win a lot of games and even Super Bowls (including hopefully McDermott!)
Belichick has Brady and a bunch of awful coaches, outside of Vrabel who did all right in Tennessee but nothing spectacular.
