Joseph Michael DeLamielleure ( ; born March 16, 1951) is an American former professional football player who was a guard in the National Football League (NFL). He was an All-American playing college football for the Michigan State Spartans. He was selected by the Buffalo Bills in the first round of the 1973 NFL Draft. He won All-Rookie Honors, after finding out a physical condition with his irregular heartbeat was not serious. In 1973 the Buffalo Bills rushing offense led the NFL in yards, yards per carry, as well as rushing touchdowns. He is also one of the first living NFL players to be tested and diagnosed with CTE (Chronic Traumatic Encephalopathy). Playing career DeLamielleure was perhaps the central figure in the "Electric Company," the Bills' offensive line that paved the way for O. J. Simpson to rush for 2,003 yards in 1973, the first player ever to break that barrier, and the only player ever to do so in a 14-game schedule. The league-leading rushing yardage mark of 3,088 yards is still the 14-game record. Only the 1978 New England Patriots have bettered that mark and did it in 16 games. Individually, Simpson led the NFL in all four major rushing categories. Joe also had the longest run in the NFL. The 2,003 yards Simpson rushed for is still the 14 game record (Eric Dickerson, Barry Sanders, Terrell Davis, Jamal Lewis, Chris Johnson, Adrian Peterson and Derrick Henry achieved their marks in 16 games). DeLamielleure was also on the kickoff return team that blocked for Wallace Francis, who led NFL with two return touchdowns. DeLamielleure played on the wedge of the kickoff return team his entire career in Buffalo. The following year, 1974, the Bills improved to 9–5 and made the playoffs. DeLamielleure was voted second-team All-Pro. In 1975 the Bills displayed one of the most potent offenses of the decade. They led the NFL in eleven categories, including total offense, rushing, rushing average, points, touchdowns and touchdown passes en route to an 8–6 record. The offensive line also allowed the fewest sacks in AFC. Simpson, behind the "Electric Company" achieved his second "quadruple crown" in three years and also had the longest run in NFL. Individually, DeLamielleure was named First-team All-Pro. 1976: Simpson again lead the NFL in rushing and DeLamielleure is named a First-team All-Pro. 1977: With Simpson injured at mid-season, the Bills pass more often, leading the
