He has the vision/anticipation and the arm to make the throws that very few QB's can. His pocket presence is uncanny. Remember how Kaaya would run straight into sacks by guys who were blocked? This dude keeps his eyes down the field and slides or runs away from the FEEL of pressure. That throw to JT on the sideline after wiggling out of the pocket was Watson/Mayfield type stuff.
The rest is up to seasoning, getting in that film room and knowing the playbook backwards and forwards in the dark while playing the piano and doing your taxes at the same time, and staying humble and leading your team. I've seen all I need to see to know that this kid has legit talent that can take us anywhere he wants to. It's up to him and the coaches to put in the work. That is the only thing, barring injury, that will limit his ceiling.
Now, don't get me wrong, he's got a long way to go and hasn't proven jack squat yet. I'm just saying it's in there. Up to the kid if he wants to be a GOAT. He can be a nerd and have a career like Drew Brees, or he can party his life away and go the way of Johnny Football.
