Less than a month after finishing his coaching staff at UCF, George O’Leary must fill it again — but not as much as he first thought. OL coach DeGuglielmo resigned on Friday after accepting an offer to coach the same position for the New York Giants. But TEs coach Eric Green, after an interview with the Buffalo Bills on Friday, called O’Leary to say he was staying at UCF. Green played for first-year Bills Coach Mike Mularkey for part of their careers with the Pittsburgh Steelers.
