Free agent PG Brian Roberts has reportedly drawn interest from the Pistons and Grizzlies. The Pistons currently have Will Bynum and Peyton Siva providing PG depth behind Brandon Jennings, but coach/president Stan Van Gundy may prefer Roberts' superior perimeter shooting -- he shot 36.0 percent from deep last year, while Bynum and Siva shot a combined 27-of-87 for Detroit (31.0 percent). The Grizzlies have a more apparent need for a backup PG since Beno Udrih is a free agent and Nick Calathes hopes to return to Greece.
