I tend to lean towards your side on this. I believe the ability to process information quickly is far more instinctual than taught. Often times we've seen QB's who play great at the college level that once they enter the NFL simply can't process what's going on in the field of play quickly enough. It's not because they haven't played the game since they were a kid. It's not that they didn't play well at the college level. They've been trained, coached and watched film for a long time. But despite all of that, their brains simply can't process the information at the speed of the NFL game despite all the years playing the game.

Some people just have that innate ability to process information quickly and some don't.
