re: Jayden is a clear cut #2 QB of all time but where does he rank amongst all players

It’s not totally irrelevant because in a lot of cases it helps the younger generations have context with some of the players. For example if you didn’t know anything about Bert Jones and just looked at his stats for LSU you could argue that Herb Tyler was better in college. Jones’ NFL career can help fans who didn’t watch him better understand what kind of player he really was.
