J.R. Smith unveils limited edition backpack

When he wasn't busy attending hip-hop concerts or getting married, J.R. Smith was spending his offseason working on a new backpack.

The newly signed Cleveland Cavaliers shooting guard teamed up with apparel company Sprayground to create a Grand Theft Auto-inspired bag that hit stores Thursday.

Smith is planning to donate 400 bags to local youth organizations in New York and New Jersey.
