Jalen is without question and elite shooter off the catch and shoot. 50% ish from 3, i believe.
Off the dribble he was not great, partly because it wasnt "natural looking (ie. His footwork wasn't great). Footwork on the perimeter definitely can be learned. He also sttuggled shooting sometimes because his motor was not ready for 35 minutes of being the complete focus of the D.
Same thing with his driving. Even though he was elite, his motor kept him from rafter-worthy performanxe at times. Only thing that didnt seem to suffer was his passing (though occasional dumb turnovers happened) and his mid range shot. If he has prepared his body for the grind this year, worked on that 3 off the dribble, practiced for a respectable left hand drive... well in that case he might just be the best guard in the ncaa
