Logo of an Ivy League football team, the Princeton Tigers, a not-so-powerful program with a powerful past. Along with Rutgers, Princeton’s program is the oldest in the world, having existed since 1869. The Tigers have claimed 28 national championships, more than any other school. They are charter members of the Ivy League, which began play as a conference in 1955. Former Tiger players who’ve gone on to play in the NFL include Ross Tucker, kicker Charlie Gogolak and current Dallas Cowboy coach Jason Garrett.
