The OP isn't in anyway a novel concept. In every game it's one QB going against the other defense. I don't see the unique point being made here at all. It's common sense that Belli is a legend and that vs. match ups don't make all that sense when people aren't playing against each other. I think he slightly undermines his point creating a hypothetical where Brady would struggle against Bellicheck's defenses because that is indirectly comparing the two players while claiming that isn't what the thread is about. But besides that, Bellicheck had great players on defense and was able to scheme accordingly. Takeaway those great players and we have seen his defenses struggle (though he gets more out of them than anyone else). Your point is basically about what an elite QB would do against Bellicheck defenses sporting Wilfork, Seymour, Ty Law and WIllie McGinest or the LT's of the world...no shyt it would be a struggle for anyone. Yet, we saw Jake Delhomme light up the Patriots defense in the SB. It's not some impossible feat, and we have no evidence that Brady would have the same amount of difficulty doing it as Peyton. So that should not have been suggested. Peyton in recent years is better against the Ravens than Brady, and Brady always shytted on the Steelers to an extent Peyton did not.
So let's give Tom Brady prime Marvin Harrison, Reggie Wayne, the Colts O-line, prime Edgerrin James, Stokley in the slot, pollard at TE and see if he wouldn't be able to eventually crack a Bellicheck defense after seeing him two times a year every year (regular season and playoffs). There's no evidence to support that. We've seen bum ass Jets and Bills teams find ways to open up Bellicheck defenses just off of familiarity. Last, this Peyton Manning is the "only QB\O-coordinator" in the league statement is pretty funny. He does nothing on a Sunday since Charlie Weis left that Brady doesn't do. Nothing. There is a reason that Tom Brady is the guy who Peyton Manning calls (because surprising to most, they're boys) when discussing how to break down an opponent.
Ask Dungy:
It is always about the offense vs. the defense, but let's not go further than that and get into unfounded hypotheticals.
