In his senior year (1936), he became the right guard in the “Seven Blocks of Granite,” a nickname given to the Fordham University football team's offensive front line.
In a game against the University of Pittsburgh Panthers, he suffered a severe gash inside his mouth and had several teeth knocked out. He missed most of the remainder of the game, until he was called in on defense for a successful goal line stand that preserved a 0-0 tie. The Rams went 5-0-2 before losing in the final game of the season, 7-6, to NYU. The loss destroyed all hopes of Fordham playing in the Rose Bowl, and the loss taught Lombardi a lesson he would never forget — never to underestimate your opponent.
