DeMar DeRozan has carved out a reputation as one of the NBA's up-and-coming young scoring stars, but it is defence that is on his mind ahead of the 2011-12 season.

DeRozan, who met with the media on Wednesday after taking to the court just hours after arriving in Toronto from California, said he is eager to get working under a revamped defensive system.

"I love it," said DeRozan, who averaged 17.2 points per game in his sophomore season — including 23.1 per in eight April contests.

Though new head coach Dwane Casey, the architect of Dallas' title-winning defence is not yet allowed to meet with his new charges, DeRozan knows what to expect.

"I can't wait to learn the system, see the schemes that he's got going on. I think it's going to be a great opportunity for us and I think it's going to be fun."
