He's shooting 40% on jumpers, far from dead eye.
He can't learn how to finish like Parker or Nash because he's 2-3 inches shorter than both of them, he is a small PG and realistically they do not finish well in the lane. The dudes ceiling is basically Ty Lawson, which is a good player but far from anything special.
Giannis isn't a sure thing, but the potential is through the roof off the fact he's 6'10 & growing while it looks like he may be a Point Forward in the future. On the flip side there's nothing that jumps out about Burke's game, dude just seems like he'll be your run of the mill PG.
