Morriss played in over 200 regular season games during his NFL career and started at center for the Eagles in Super Bowl XV.
[13][14][15] After he was waived, Morriss accepted a position with the Patriots as the offensive line coach for the 1988 season under Raymond Berry.
[17] After a recruiting scandal forced the resignation of Mumme at Kentucky, Morriss was named the school's interim head coach in 2001.
Morriss's Kentucky Wildcats kicked a field goal to take the lead over LSU with 11 seconds left, only to lose on an 80-yard Hail Mary pass as time expired.
Seconds before the Hail Mary, Morriss was doused with Gatorade by quarterback Jared Lorenzen in a premature "victory bath".
[21][22] Morriss resigned from Kentucky to accept the head coaching job for the Baylor Bears in December 2002.
[29] In 2006, Morriss's fourth year, BU had a disappointing 1–3 non-conference mark (including a loss at home to Army).
However, the momentum was stunted when quarterback Shawn Bell was injured in a loss to Texas A&M,[31] and Baylor lost their final three games, finishing the year at 4–8 (3–5 in the Big 12).
[37] In December 2008, Scott Conley was removed as head coach of the Texas A&M–Commerce Lions football program after a 24–27 record in five seasons.
On January 7, 2009, Morriss was offered the job to succeed Conley by athletic director Carlton Cooper and university president Daniel Jones.
[41] After Morriss's first season, players from his football team coordinated an effort to illegally remove all copies of a student newspaper from campus because it contained an unfavorable article about a teammate who had been arrested on drug charges.
[43] The Lions christened their newly renovated stadium by routing Upper Iowa, 33–10, giving Morriss six straight wins as head coach.
2012 produced an identical record of 1–9, the lone victory coming over long time rival Texas A&M–Kingsville, 21–14 in overtime.
