Weekend mail call:Benny from San Mateo, Calif., wants to know how important was it for the 49ers to get a third-round compensatory pick.Bill Williamson: The 49ers received the final of the third-round comp picks. It is the 100th overall pick and the last pick of the second day of the draft. The expectation was the 49ers would get a third or a fourth-round pick, so getting the third rounder is important. The comp pick can't be traded, but it does allow the 49ers to be more flexible in dealing one or both of their two third-round picks, which are No.
