I've always believed that the best QBs get smarter as they get older, and the things they can no longer do physically are replaced by the things that they do mentally, to maintain their competitive edge. I've seen it so often, with so many of them, that like most people, I've tended to just take it for granted.
The Aaron Rodgers of 2021/22 may not be as agile, have as much pop on the ball as he did 10 years ago, but the way he sees the game, and plays it, controlling it, has easily offset the reduced physicality he once had.
I'll take a smart, older QB, over one who is young and full of exuberance anytime. They just seem to exemplify what the whole thing is really all about.
I can't think of any QB in the league, outside of Rodgers, that I feel can win a game for us if we're getting the ball, down by 2 to 6, with one minute left, and no time outs. He can just plain flat out move the team down and get that score. In fact, I doubt too many people out here feel that when we're in that situation that the game is already over. With him, it could be another magical finish.
Just my opinion.
