Career
Drennon was a prominent guard for the Yellow Jackets of the Georgia Institute of Technology. He was said to be one of the tacklers of Roy Riegels in the 1929 Rose Bowl after he ran 65 yards in the wrong direction. This led to a blocked punt by Vance Maree and an 8 to 7 Technical victory.
Coach William Alexander called him the "best all around guard that ever put a cleat into Grant Field."
He received an appointment to West Point in 1930.
