he has plenty of arm strength for the NFL and he's plenty accurate to. Hell he's got a stronger arm that half the NFL at this point. Accuracy he's had and he can even learn more and go farther. Especially with a system and coach like reid. Hell peyton has a ****ing NOODLE arm but he does what he does cause he's smart and he has the system perfectly fit to him.
I'm a firm believer that accuracy is a product of the system that you put around your QB. Granted there is natural accuracy, that i think barkley and geno both have. But system and coaching can take it to that elite level, ala geno in his air raid system with his teams system
