Here's the problem. Take him in the 1st round, (you and I both know he won't sit long if at all), and you create a recipe for failure. He lacks experience and is inaccurate...IN COLLEGE. In the pros he will become David Carr...drop back, see 1st read covered, run. Wash, rinse repeat...wash out of league. He doesn't 'throw his WR's open' One weakness is he waits for someone to be open before he lets it go. You an learn that while watching. He will be playing if he's in the top 5.
Seriously, you will wish this guy was never on your team. Some team is going to suck bad and get Sam Darnold, who is infinitely better than anyone in this class. That will be the lucky franchise.
