This is not "another Tony Allen" as Walker was playing through this at pre-draft camps and STILL IMPRESSING teams. The dude has grit, determination, is only 20 and wants to be a star. He WANTS to be an NBA talent, he doesn't have that attitude of some guy who already thinks he's done enough once he breaks a sweat. I think he fits in with this team and will take away great experience from Ray, Pierce and KG (especially Ray Ray I feel like).
He has time to heal and then he'll have time to impress. He will be an awesome impact player on the C's second-line. 6'5" Larry Johnson.
