lol... you can't be serious.
You failed to mention that Randy Moss played with Brady for 16 healthy games in 2007, 16 unhealthy games in 2009, and 2 games in 2010.
"The most talented tight end ever to step on a field"- I love Gronk, he is awesome, but A) he can't stay healthy, and B) as a pure pass catcher, and therefore as someone who would make the passing game look better, there are about six tight ends in football right now who can do that. Gronk is awesome primarily because of his blocking and pass catching skills combo. Any way you look at it, I would hardly say that having Gronk from 2011-present, with all of the injuries, would fill in for all of the deficiencies on offense.
Brees has always had a much better offense than Brady. The Saints have a bunch of B+ caliber players at every skill position and a great offensive line. Brees has 2-3 outside guys each year that are highly capable of big plays.
"Insanely good" is an understatement for Manning. He has never even had a season where he has less than TWO pro-bowl caliber outside receivers. In Indy, it was Harrison and Wayne, two Hall of Fame caliber players. In Denver, it's D. Thomas and Decker/Sanders, and you can sprinkle in a whole bunch of other weapons like Stokley, Clark, Faulk, Garcon, J. Thomas, Welker, etc. etc. I have no idea how Manning is known as "the whole team" when GMs do everything in their power to give him more weapons than a US Nuclear Stockpile. Outside receivers stretch the field and he can do whatever he wants underneath. Brady has had exactly one outside receiver for two years who was even a major threat.
Better than Marino's cast? I guess you have not heard of the Marx brothers.
