Football
Blake was a prominent end for Dan McGugin's Vanderbilt Commodores football teams in 1903 and from 1905 to 1907. He was also a punter and drop kicker. As a punter, one writer claimed others considered him "the best in the country." He was selected All-Southern unanimously each and every year he played, and Vanderbilt won the Southern Intercollegiate Athletic Association championship in all of his years. In 1915, John Heisman called Blake one of the greatest players in Vanderbilt history, along with Ray Morrison and Owsley Manier. Grantland Rice once said about Bob Blake, “he was the only halfback who never lost a yard around right end.” A fellow student at Vanderbilt once said of Blake "He is an athlete and this has been one great factor in making him popular, but Bob Blake would have been a popular man if he had not been an athlete. In the third place he is interested in and takes an active part in every phase of college life. In the fourth place he has maintained himself well in scholarship, while not a brilliant student, he has, in my opinion, made a record above that of the average student." In the opinion of fellow Vanderbilt player Honus Craig, Blake was the South's greatest player. Blake was chosen for an all-time Vandy team in 1912, and for an Associated Press Southeast Area All-Time football team 1869-1919 era.
1903
Both Blake and teammate John J. Tigert were Rhodes Scholars. Blake broke his wrist in the Sewanee-Vanderbilt game.
1904 and 1905
Bob Blake did not play in Dan McGugin's first year of 1904, but resumed play on the 1905 team.
1906
Vanderbilt won a major intersectional contest in 1906 when it defeated Carlisle 4-0 via a single, 17-yard Blake drop kick, "the crowning feat of the Southern Intercollegiate Athletic Association season." The score was 4 to 0, as field goals then counted for 4 points. College Football Hall of Fame inductee Albert Exendine was playing for Carlisle. Frank Mount Pleasant missed four field goals.
1907
He made Walter Camp's All-America Honorable Mention in 1907, as well as the first team All-American selection of Michigan coach Fielding Yost. Blake threw the pass to Stein Stone on a trick double-pass play which set up the score to beat Sewanee in 1907 for the SIAA championship, which was cited by Grantland Rice as the greatest thrill he ever witnessed in his years of watching sports. Blake missed two kicks on a slippery field in the 8-0 loss to Michigan.
