Walker is in his 13th year on the Delaware State staff. He is also the team's recruiting coordinator, in addition to assisting with opposition scouting reports.
Walker primarily works with the DSU post players. During the 2011-12 season, his work with the Hornet big men was instrumental in the team's school-record 192 blocks, shattering the record previously held by the 1989-90 squad. Delaware State was tops in the MEAC and fifth among all NCAA Division I teams at 6.6 blocks per game last season.
In addition, DSU power forward Marques Oliver moved into first place on the team's list for career blocks last season. Oliver enters his senior season in 2012-13 with 161 career blocks. Also, Oliver established a team single-season record with blocks during the 2011-12 campaign. Another Walker pupil, freshman Kendall Gray, had 54 blocks in just 17 games last season. Gray was tops in the MEAC and ninth among all NCAA Division I players in blocks (3.2 pg) when he was sidelined with a season-ending knee injury.
Walker helped lead the Hornets to three consecutive MEAC regular season titles from 2004 to '07, during which the Hornets posted a league record of 46-8 (.850). The Hornets appeared in three consecutive MEAC Tournament championship games, capturing the title and accompanying NCAA Tournament berth in 2005. The following year, Delaware State defeated Northern Arizona on the road in the National Invitation Tournament for the team's only national post-season win. The Hornets also appeared in the 2007 National Invitation Tournament.

Walker was head coach at Shaw University, while Jackson was running the program at Central Intercollegiate Athletic Association rival North Carolina Central. In Walker's best season at Shaw, the team posted a 22-6 overall record and reached the semifinals of the CIAA Tournament in 1995. The Bears finished in the Top 10 of the Black College poll during two of Walker's seasons. In 1998, he coached a team of U.S. collegiate players to a bronze medal at a tournament in Russia. From 1987 to '93,
Walker was an assistant coach at Indiana University of Pennsylvania. IUP was ranked number one in the NCAA Division II poll during parts of three seasons while Walker was on the staff.
