Yeah, Manning wouldn't be as effective on the Dolphins or Jets, neither would Brady or Joe Montana or Dan Marino for that matter, but they would be much better teams with him and he still would be a great QB.
Why is it about Pats fans not being able to admit Manning is a great QB? He's going to the Hall, he has the numbers and he's got a ring. You have nothing left to criticize him about. Let it go.
I understand you defending Brady, he's great and he's your QB, but come on, bashing Manning the way a lot of you do is ridiculous.
Most Pats fans recognize that Manning is a great QB, but not the greatest. That is why a lot of people get pissy about him, because he has been made out to be the GOAT by a lot of media people and a lot of people have definitively stated that he is the best in the game today. Patriots fans who feel differently are obviously going to defend their quarterback (who is the best in the game today, yesterday, and tomorrow). Manning gets an unwarranted pass for his recent "struggles" because of injuries to the players around him, but when those same heads were talking about him being better than Brady they ignored the talent around both of the quarterbacks. There is a desire to argue in favor of their player amongst Patriots fans, as there is for every fan in the NFL.
