The 1947 season was another strong one for Speedie. In a game against the Buffalo Bills, he tied a professional football record by catching a throw from Graham and running 99 yards for a touchdown. He finished the season as the league leader in receptions and receiving yards as the Browns won another championship. His 67 catches and 1,146 receiving yards, in fact, were the second-best in pro football history after Don Hutson of the Green Bay Packers, who caught for 1,211 yards in 1940. Speedie was named by news outlets as a first-team All-Pro. Speedie's success in 1947 came as he, Graham and Lavelli gelled as a passing and receiving unit, having studied hours of tape and worked on their technique and coordination. Speedie studied how defensive backs moved their feet and tried to break into the open by exploiting mis-steps. They experimented with screen passes and made modifications to common receiving routes to exploit the weaknesses of defenses.
