hey man you fucking asked the question "Aaron rodgers...you say its situation, but are you really suggesting that aaron rodgers would be just as good if he had to start for green bay immediately." YES, THAT IS EXACTLY WHAT I AM SUGGESTING. Or at least I am agreeing with your assumption that someone else suggested it. Don't bitch at me because you received a question to an answer you asked. You can read all the books you want, take all the classes you please, run through simulations till your brain explodes but there are just some things you can simply never truly understand until you actually go out, do the job, and experience everything first-hand. What makes football (maybe sports in general) different from literally any other task/duty/profession in the world that this would not be the case for quarterbacks?
At any rate, considering there are numerous samples of guys showing immediate success as a starter (and no Killah, sophomore slump doesn't necessarily mean negative things... opposing teams have film on this guy now, still learning, perhaps simply random variance / regression to the mean) I really don't see how one could definitively say it's the reason for the lack of success of the ones that don't. Teams should play the guy that gives them the best chance to win. If they can afford to groom their QB-of-the-future on the bench for a while, great. But when your choice is Chad Henne and Matt Cassel gets injured, well hey maybe Bortles should be out there after all and Bridgewater is going out there whether he wants to or not.
