Lynn Swann and John Stallworth
If you take stats out of the equation, Swann and Stallworth were a big play waiting to happen. Playing in a run-first Steelers offense, this duo achieved Super Bowl greatness.
Cris Carter and Randy Moss
Carter and Moss played together for four years and combined for 93 touchdowns. Need we say more? This duo might be the most dangerous of all time.
