I can only go in my lifetime:
3- Noll/Bradshaw- could be 2, but for a couple bizarre drops/catches (Jackie Smith, Lynn Swann) the 70's Cowboys were a better coached/QB'd team, but lost.
4- Madden/Stabler- the most contemptible duo ever, and with good reason. They are the figureheads of the most sterling antagonists the NFL will ever know. And they were great.
5- Walsh/Young- the originators of the 'efficient' NFL offense.
6- Shula/Marino- they were brutal. Marino got nailed all the time... after he released the ball and hit Clayton or Duper. It was insane how little he got sacked. Jim Jensen was a frickin nightmare of an outlet receiver... Hello, Wee Welker... yes, Jim Jensen. They were good
7- Reeves/Elway- they were better than us in our prime, and better at quarterbacking than..
8- Belichik/Brady- They've won, and they've done it efficiently, and with great kicking and the amazing stupidity of their opponents.
Don't forget the San Diego interception/return some years back.
Belichik belongs at the top of this list in many ways, but Brady would've never survived the game that the upper QB's did. He's weighted up by BB. #8
9- Holmgren/Favre- you were dead at any given moment.
10- Coryell/Fouts- the absolutely most fantastic MR(s) Irrelevant the NFL produced!
... sorry to Grant/Tarkenton and Levy/Kelly. always a bridesmaid....
