In a book on the 1958 Championship game, Frank Gifford stated that Roosevelt Brown was the best athlete on the team. He played left tackle in that game but when DT Roosevelt Grier was injured, Brown went into the game and played both offense and defense for the better part of 3 quarters. It seems that they could only carry 35 men on the roster so there was no backup defense tackle to go in for Grier. Brown was his backup.
