Not saying he should stay depending on some things. Other factors might make it wise for him to go even though I agree with you.
AR reads the field very well. Yard markers, first down markers, sidelines, end zones, all of it. It's the defense he doesn't read so well. He would be a great QB if it weren't for all the defenses that keep showing up. As far as accuracy on NFL throws, Napier needs to send a note to his offensive coordinator to call more NFL throws. He sometimes struggles with the college throws. He will get better, but it will take time.
Better chance to develop but could be exposed at tge same time. Always take the sure money over the chance to have more. Bird in hand baby.
I'm not sure NFL scouts are as high on AR as TV talking heads are. There's not that much hunger for an inaccurate thrower.
If he's going to save himself physically for the NFL, I don't see why he'd comeback. Or why we'd want him back. He's so explosive and he could tuck and run way more for big plays, but I don't think he wants to risk injury. And I definitely understand because NFL money can change his family's life.
