Read the thread, I didn’t bring up Brady first. But you can’t say, “look at past generations, they turned out better
because they got to sit for a few years first” because everybody sat at first. No rookies would ever start from game one, so you don’t have any examples from that group to compare with those that sat.
Today, we get guys that start from game one and we get guys that don’t. Most starting QBs in the NFL today start as rookies. But there are still guys every single year that get to sit and learn. Yet those guys rarely end up being legit starters. Mahomes is the obvious exception here.
Not only that, you’re taking guys from an era where college offenses were extremely different from NFL offenses. So guys actually needed time to learn NFL concepts. That isn’t true anymore, because modern college offenses share concepts with the NFL. You learn by going out and playing, so that’s what NFL teams are doing. If there was evidence to suggest otherwise, don’t you think more NFL teams would do it?
