Raiders quarterback Jim Plunkett completed 230 out of 379 (60.7 percent) passes resulting in 2,935 yards and 20 touchdowns.  His favorite target was tight end Todd Christensen, who led the NFL with 92 receptions for 1,247 yards and 12 touchdowns. Wide receivers Cliff Branch and Malcolm Barnwell combined for 74 receptions, 1,209 yards, and 6 touchdowns. But the largest impact on offense was running back Marcus Allen.
