It has been difficult for rookie Bill Walker to find floor time for the Celtics this season, but his former Kansas State teammate believes in his future in the NBA.

"It's been hard for him," Beasley said. "I talk to him. But he has to keep pushing. He's a great player. A great athlete. The sky is the limit for him. He's 6-5, 6-6, 240 pounds. But he moves like he's 215 and jumps like he's 190 pounds. There's a lot you don't know about Bill. Bill's a 3-point shooter. There's a lot to his game that the world hasn't seen yet and is yet to come. Once everyone sees what he can do, it's going to be something special."
