Brady has played for the best coach possibly ever his entire career. Brady has played for the best football organization in the league. Brady has had good to great protection and O-lines his entire career. Brady has had top 10 defenses almost every year of his career, and also a few top 5 defenses. Brady has had fantastic talent to throw to. From Moss to the murderer and to Gronk and Welker and everyone in between.
It has been the perfect storm for a great QB.
But lets go back 10 years and have Brady and Rodgers switch teams. Rodgers obviously would have massive success in New England. But would Brady have had success on GB? Brady can't move, so he may have been crushed behind shitty protection. He can unload the ball quickly, but I think he looks a lot more average if he plays for the Packers. And then he would have no help from the defense and even more pressure on him. And he would not be throwing to all the talent he would have had in NE. And he would have some fucking Donk coaching moves and calls made all the time.
If I had a choice to start a franchise I would choose Rodgers every time over Brady. He can win anywhere on any team.
