So my point was less about Belichick verses Brady and more about how a well run system with a great coach is more likely to lead to multiple SBs than having a great Q.B.
I would think another example of this would be the record setting "The Greatest Show of Turf" offense of Rams head coach Mike Marsh.
I mean, when you can take what was before being acquired by the Rams was pretty much a journeyman QB with limited foot speed, BUT with one of the quickest release arm motions ever(I'm talkin' Kurt Warner here of course), and which perfectly plays into a timing and spot location type pass offense, you end up winning a Super Bowl and ALMOST win another one, IF you're not out-coached in your second SB appearance by guess who?
Yep, Bill Belichick.
Yep, the Rams should have beaten the Pats in SB XXXVI, but Marsh got out-coached by Belichick when Belichick's game plan was primarily geared to stop the pass at the expense of stopping the run. But, Marsh failed to later adjust his game plan and switch to more a running game, AND a running game featuring the great Marshall Faulk and of which the FEW times the Rams went with it in that game was shown to be very effective. And YET inexplicably, Marsh primarily continued on with his pass offense throughout the game, and thus the result being totally out-coached and thus losing a game the Rams SHOULD have won.
(...and while I know this sounds a lot like "Monday morning quarterbacking" here, you should have HEARD me yelling at the TV set I was watching that game on, and yelling at Marsh in particular to switch to more a running game)
