Mario Chalmers is an old soul. He has an almost preternatural calm on the court, as if he's been there not only his entire lifetime but also a few others. That's a very good thing for a point guard and team general. His rookie mistakes are more like sophomore mistakes. The offenses he leads have a tendency to take on his smoothness, but his best trait may be his defensive tenacity. Sometimes he has a little too much of it and gets into unnecessary foul trouble, but that's a problem any coach will take. As good as Chalmers is, the choice is certainly arguable. Michael Beasley is another special rookie with the skills and confidence to be a star in the NBA. He just happens to be a young soul (his favorite show is SpongeBob SquarePants, for crying out loud). Look for Beasley to be the best sophomore.
