Had Walker been able to go straight from high school, he would've been a lottery pick. Now, the pros are waiting to see how the knee injury heals, and if the explosiveness is still there. Of course, the longer you hang around college, the more they look for the warts and the less they draft on potential. They will look more closely at his long range game and ball handling this year than they would've if he could've gone before last year. Still, if his explosiveness is back he is a lottery pick either this year or next.
