Hadn't seen this anywhere else. Doc has a lot of nice things to say about Walker. Sounds encouraging.
Some quotes:
"Clearly, he would have gone earlier if he projected healthy," Rivers said. "I think he would have been mid-first [round] definitely to low-first. But everyone was scared about his knee."
"He clearly can earn a position if a team is willing to take the chance."
The question is what position can he play since, considering his height, he's a classic "tweener."
"He's that in size but in body he's a three," Rivers said. "I think he would struggle even more guarding twos. He's athletic enough to, but his body tells you he's a 3 because he's so strong.
"He attacks the basket, too, and will live on the foul line. He's got to work on his ball handling a little bit, but if he comes off the cuts, he's going to live on the foul line."
Rivers says he believes that Walker could excel in a transition game and could be even more productive as a post-up guard.
"Billy's great in transition," Rivers said. "But I think Billy's going to be a great post guard. I don't know if he knows that yet, but I think he will be."
