The 1906 college football season was a year of change. Following controversies in 1905 over the increase of violence and professionalism in college football, a number of rule changes were implemented in 1906. The most lasting change introduced in 1906 was the forward pass. Several of the players selected as All-Americans in 1906 gained attention for their use of the new tactic. These include Eddie Dillon, the first Princeton quarterback to make use of the forward pass, and Yale's Paul Veeder and Bob Forbes who combined for one of the first important pass plays, a play described in one history of the game as follows: "The only other significant pass that season was thrown by Yale, which gained a first down that led to victory over Harvard, when Paul Veeder threw thirty yards to Bob Forbes." The Eastern powers dominated the game of college football in 1906, and players from the Ivy League dominated the All-American selections. Both the Princeton Tigers and the Yale Bulldogs finished with undefeated seasons and played each other to a 0–0 tie on November 17, 1906. Out of 15 players recognized in the NCAA Record Book as consensus All-Americans for the 1906 season, 13 played for Ivy League teams, and 7 played for Princeton or Yale. Only two players from "western" schools were first-team selections—quarterback Walter Eckersall from the University of Chicago and center William Thomas Dunn from Penn State. The only unanimous first-team All-American in 1906 was Yale end Bob Forbes. Other players who were named to the first team by at least five of the eight selectors reflected below were end Caspar Wister of Princeton, tackle Lucius Horatio Biglow of Yale, guard Francis Burr of Harvard, guard Elmer Thompson of Cornell, center Clarence Hockenberger of Yale, and halfback Hugh Knox of Yale. The Washington Post in December 1906 wrote of the difficulty involved in selecting eleven players for an All-American team:
"A big problem confronts the person who this year undertakes to select eleven men for a football team which he wishes to call the best in the country. There are more good men than ever before, among the minor elevens, because, with a premium, placed on speed rather than on weight, the lighter men have had a better opportunity to distinguish themselves. It would be possible to pick at least three teams which would make things mighty interesting for each other. The East has completely eclipsed the West this season, and that somewhat simplifies matters. The Western teams failed to grasp the possibilities of the new rules and players of that section who were brilliant last year did not get an opportunity, to shine this year in the new game. Walter Eckersall, of Chicago, appears to be the only Westerner who has a right to be in the All-American team this fall."
In announcing his All-American team, Caspar Whitney wrote that he had weighed character as a factor in his selections:
"This eleven is chosen, after a season's observation, with a view to collecting the most resourceful, strongest all-round team under the new rules. No man whose amateur status is a matter of question or whose play has been unsportsmanly is eligible to this national team, which, in keeping with its honorary nature, I endeavor to confine to sportsmen."
