Good point and I do agree that we shouldn't just believe (I'm changing your wording a bit) ANYTHING just because the media says so.
Again, my point was the difference for Fromm and Manning/Luck, even in the article you linked no one was questioning if Manning had a strong enough arm for the NFL, just that his arm strength was a weakness (and from some other articles I've read, there is speculation that was started by Leaf's agent and media being the media just parroted that rather than reviewing. And I've also said, I don't necessarily believe the reports about Fromm's arm, just that is what is being reported.
Do i think that Fromm is Peyton Manning, obviously no. What i was saying is simply that i feel he is being overlooked by the media hype train, because they want to hype the "next big thing" with the "live arm"
