Dwight Howard hasn't been a Laker for long, but he's already impressing his coach and teammates. 

The eight-time All-Star signed with Los Angeles in free agency and wants to do everything he can to help the Lakers improve this season. First-year coach Frank Vogel said Tuesday that his "centers have really impressed" him, giving credit to Howard for his leadership.

"Dwight Howard has been all business since he came in this time around," Vogel told reporters (via ESPN). "We're asking our whole group to have a seriousness about ourselves. He's been an all-business type of guy. It's really helped us to be focused and working on the task at hand."

Howard played just nine games last season because of injury and he's played with four different teams (Wizards, Hawks, Hornets, and Rockets) over the last four seasons before joining Los Angeles.
