He also earned a letter in track that spring. As a junior, he rushed for 666 yards (5.2 per carry), averaged 11.3 points in basketball and was named a second-team All-American in lacrosse. In his senior year, Brown was first-team All-American in both football and lacrosse (43 goals in 10 games to tie for the national scoring championship). He averaged 6.2 yards in running for 986 yards -- third most in the country despite Syracuse playing only eight games -- and scored 14 touchdowns. In the regular-season finale, a 61-7 rout of Colgate, he rushed for 197 yards, scored six touchdowns and kicked seven extra points for 43 points. Then in the Cotton Bowl, he rushed for 132 yards, scored three touchdowns and kicked three extra points. But a blocked extra point after Syracuse's third touchdown was the difference as TCU won 28-27.Professional Career

Lacrosse
Brown was every bit as good a lacrosse player, with the National Lacrosse Hall of Fame stating that he was "widely considered to be the greatest lacrosse player ever." http://en.wikipedia.org/wiki/Jim_Brown
At Syracuse University, Brown's all-around athletic ability became evident, as he lettered in four sports and was voted the school's Athlete of the Year in 1956-57. Brown was a Second Team All-American Selection in 1956, and earned First Team Honors in 1957, finishing second in the nation in scoring his senior year. Many believe his last game was his greatest moment as a lacrosse player, as Brown scored five goals in one-half of play against the nation's top players in the 1957 Collegiate North/South All-Star game.http://www.lacrosse.org/museum/halloffa ... prof_id=35
