For me JA is standing in the pocket looking to make a throw instead of trying to make magic happen (aka Hero Josh). Multiple times yesterday he was standing tall and throwing balanced as opposed to feeling the pass rush and trying to throw on the move or with his weight on his back foot using all arm. So it's less wild throws because he is mentally calming himself and that is leading to more throws with better mechanics which is leading to better accuracy. Like a lot of qb's he isn't inaccurate if he has time and space and the change in his thought process to try and wait to make throws in the pocket seems to have helped him.
It's really a pretty rare thing to see this much improvement and it speaks to JA's abilities and mindset that he can get it done. If he keeps this up he will definitely be a franchise qb in the leagues mind, possibly by the end of the year with the Bills making a deep run in the playoffs. 😁
