It was pretty impressive that Allen took his team to the AFC title game in his 3rd season without much of a running game to help him out. And his accuracy improvement was extraordinary. It remains to be seen if he can duplicate that this season of course.
2 things happened to Allen that happened to Dak:
1. He got a some real passing weapons and a legit #1. Diggs
2. He matured like most QB's from their rookie years
1 thing happened that has never happened with Dak or Romo
1. His team built a defense
But probably the biggest thing happened to Allen........................Brady went to the NFC
You think Allen makes it to the championship game with the 31st ranked NFL defense? I doubt he even makes the playoffs.
