James Street, the quarterback of the University of Texas' 1969-70 national championship team, died Monday at 65.
A business associate, Serena Fitchard, told KTVU News in Austin, Texas, that Street died of a heart attack.
A reserve at the start of his college career, Street took over the starting role for the third game in 1968, and the team went 20-0 with him under center that year and in the title-winning season that followed. Included in the run was the 1969 regular-season finale in which No. 1 beat No. 2 Arkansas 15-14, a contest dubbed "the Game of the Century."
The Longhorns subsequently beat Notre Dame 21-17 in the 1970 Cotton Bowl to clinch the national title.
"We lost a great man, a great friend of mine, who has done so much for the University of Texas, the state and, really, America," Longhorns coach Mack Brown said, according to the Austin American-Statesman. "His memory and his accomplishments, really, his influence ... He will be missed."
Street also was a star pitcher for the Longhorns, going 29-8 with a perfect game and another no-hitter. He helped guide Texas to three appearances in the College World Series.
"The coaches, staff members and players on the Longhorn baseball team are shocked and deeply saddened by the news of James Street's passing," Longhorns baseball coach Augie Garrido said in a statement. "He is in the minds of Texans an immortal Longhorn, the ultimate father, courageous leader, and eternal champion, not only in football but also as an All-American pitcher. He made everyone he met and many that he never met better people. His contributions to our society are immeasurable."
After his athletic career, Street embarked on a career in finance. One of his sons is San Diego Padres relief pitcher Huston Street.
