Check above, I found something that shows exactly that.I bet walker would look pretty good in those comparisons as well. Walker is like a really really good defender/rim protector. It was pretty well established that he was an amazing rim protector in college as well. Im certain that it was not secret to the other teams in his conference that he was amazing at protecting the rim. Didn't make him any less effective. He just has really good instincts and timing and moves well to go along with his size. He is just an amazing rim protector.
