Basketballese

During the long, dreary, wet winter I amused myself by watching college and Pro basketball on the idiot box. Will one of you basketball-savvy gardeners please tell me what RPI stands for in basketballese?

Detroit bounced back nicely with a 65-50 victory over Connecticut. The Shock never trailed in this one, and led by as many as 25. Fast break points were a key, as was the Shock's scoring production “in the paint,” as the area close to the basket is known in basketballese.
