[1] Stallworth was selected 82nd overall in the fourth round of the 1974 NFL draft, a class of which he was one of four Pittsburgh Steelers picks who would eventually be inducted into the Pro Football Hall of Fame.

[2] Scouts from various NFL teams observed him run the 40-yard dash on a wet track at Alabama A&M University and were disappointed by the results.

Steelers assistant personnel director Bill Nunn was the only person to stay an additional day and watched Stallworth run a better time on a dry track.

Nunn also had obtained the only college game film of Stallworth that existed through his relationships with HBCU coaches, and it was alleged that he withheld it from other NFL teams.

Stallworth battled a series of fibula, foot, ankle, knee and hamstring injuries that forced him to miss 44 regular-season games.

In Super Bowl XIII, Stallworth caught a record-tying 75-yard touchdown pass from Terry Bradshaw that was crucial in the 35–31 win over the Dallas Cowboys.

With 12 minutes remaining, Bradshaw dropped back and threw it long to Stallworth, who caught it and beat Rod Perry to the end zone for a 73-yard touchdown that paved the way for the Steelers' 31–19 win and their fourth world championship.
