A couple things.

Early in the season his mechanics improved imo. Now he is throwing ball low and with his core again. Last week a ton of batted balls.

All season he throws short on crossers that avoids ints but Wide open receivers have to go to the ground to catch the ball. Probably an accuracy issue due to mechanics.

Routes to the flat and fades have zero touch. Ball comes out low and hot. Again mechanics.

I wouldn’t be surprised to hear that he is dinged up that happens. I would be surprised if he admits he is not 💯
