No, there isn't, and has never been. Brady was an It's just my opinion that Belichick elite QB, like other elite QBs. Brady has been to what, 9 SBs in New England? Rodgers and Brees got to 1 each. Even if you think Brady was better than them, by how much, 9 times better? No.
There is not a huge gap between elite QBs. But Brady is the only one that got to so many SBs. It's because of the coach, and his system. It was just better than the rest. No other coach had close to as much success with an elite QB. It was just the perfect storm of great coach and QB coming together. No coach is going to do well with a bad QB.
