I hope Walker keeps improving and earns some rotation minutes, but I really don't see his ceiling as being nearly as high as a lot of people. I love his aggresiveness, but his jumper isn't there yet. And I hope this will change as his knees get stronger, but I really don't see him as an outstanding physical athlete. Yes, his vertical is amazing and he is very strong, but quickness is more important and I don't see much quickness at all.
