I'm sure there are a lot of things that Pickett is going to be working on this offseason.
Every quarterback works on his craft, trying to improve in any way they can. Mechanics can be improved, but only from the pocket with a solid base and being able to step into a throw. Every other type of throw becomes more reliant on adjustments and individual talent. When a quarterback is on the move, they can't use the same mechanics unless they are able to stop and reset their feet. You see guys like Mahomes make all those off-schedule throws, throws on the run, multiple arm-angle throws, no-look throws, throws off his back foot, etc... That shit is pure talent. Some guys can do some of that. Some can do very little of it and everything has to be perfect for them to succeed. Guys like Mahomes are just so rare. They can do anything because they have rare ability to be able to adjust to any variable and make accurate throws. The more of those secondary skills and abilities that guys have in their toolbox, the more answers they have on the field.
Pickett appears to have the ability to do some of that. He isn't Mahomes, but who is. He will work on what he can....and do the best he can to manage the stuff he can't do. That's the struggle when playing quarterback....trying to do everything you are capable of without trying to do too much or things you can't do.
I'm excited to see what he can become when he maximizes all his talents.
