He understands the mental part of the NFL game already while working out of a pro system in college. He knows how to look off a DB and he makes good decisions. Can truly manage a game. He goes through progressions really well, good mechanics through play action and bootlegs and his overall throwing mechanics are good.
I don't see a problem with his arm strength. I think it's good enough to make all the throws. Is it great? No but I think it's good enough to get the job done. He is very accurate on those short-intermediate throws. He has also shown up in the big games -
