But how can this ever be known? It's impossible to know. I'm not saying every rookie QB should be thrown to the wolves, some may take longer to develop. You evaluate this on a player-to-player basis. But to give a blanket statement that a QB must sit to develop, or would've became a great QB if he hadn't started so early, is categorically false. After well over 60 years of football, there's still no evidence to suggest this and even still, the league is constantly changing over the years.
