Not so sure Brady has had a ton more weapons. He has however had better coaches. Yes, Gronk was a star, but beyond that it seems they've mostly made it happen with good players who do their jobs rather than All-Pro type talent at the skill positions. Their wide receivers have been a pretty pedestrian group. Nice players like Welker, Amendola and Edelman have had a handful of 1000yd seasons in the past decade. Same with their running backs - only a few 1000yd seasons in the past decade.
They take nice players like James White and make them more effective than they would otherwise be on most teams by using them to best effect.
One could certainly argue that until the last couple of seasons, it's actually been AR who's had the advantage in terms of weapons. Now, AR had to do some of what he's done over the seasons because the offense as implemented by MM needed him to do that to win games. I'm hopeful that ML finds a way to make AR more effective without him having so regularly extend plays with his legs to make the offense go.
