Dorrell Green 

(Football, 1994-97)

A fierce hitter with a high football IQ, Dorrell Green was not only one of the finest defensive backs ever to suit up for the Blue Hens but one of its strongest team leaders for Hall of Fame head coach Tubby Raymond during his memorable career. 

A 1998 Delaware graduate, the Capitol Heights, Maryland native started at safety his final three seasons while leading UD to a mark of 31-8 with three NCAA Tournament appearances, including a semifinal berth as team captain in 1997 and a trip to the second round in 1995. 

One of only two UD players to earn first team all-conference honors three straight years, he also earned third team All-American and first team All-East honors as a senior in 1997 when he posted 124 tackles — a still-standing record for a member of the UD secondary — and intercepted five passes. He also recorded 91 tackles and nine interceptions as a junior in 2016 and 97 tackles and five picks as a sophomore in 1995.

An in-state standout from Camden, Delaware. and a 2010 UD graduate, Casey set numerous records and led the team to a 14-6 record, the Colonial Athletic Association Tournament title, and a berth in the NCAA Tournament as a senior in 2009.
