Coaching career
Rutgers
Flood was hired as the offensive line coach for the Scarlet Knights in 2005. In 2008, he was promoted to assistant head coach under Greg Schiano. On January 31, 2012, Flood was hired to replace Schiano, who had been named the Tampa Bay Buccaneers' head coach.

Flood led the Scarlet Knights to his first ever bowl victory and the sixth overall for Rutgers over the North Carolina Tar Heels, 40–21 in the inaugural Quick Lane Bowl, giving Rutgers a respectable 8–5 record in its first Big Ten season.
Controversies over player misconduct
The 2015 football season was marred by alleged misconduct by Flood and the arrests on violent felony criminal charges of several players. There were doubts that Flood would be coaching the season opener and some speculation amongst news media and fans about the possibility of Flood's firing or resignation. The 15-member Rutgers Board of Governors, one of the school's two governing bodies, met with university presidentRobert Barchi on September 11 in a closed-door emergency session to discuss ongoing "athletic matters" and the potential for litigation.
On May 24, 2015, redshirt freshman defensive back Darian Dailey was arrested in Florida on felony robbery charges.
In late August 2015, Flood suspended five players for the first half of the season opener for breaking curfew.
On September 3, 2015, six players were arrested and charged with felony assault, armed robbery, criminal restraint, conspiracy, riot, and weapons possession; these charges stemmed from an April 26, 2015 incident in New Brunswick, New Jersey characterized as a home invasion robbery. Five players were dismissed from the team moments before the season-opening football game against the Norfolk State Spartans. A sixth player was arrested a few days later. Several arrested players had previous arrests for other criminal charges.
One of the suspects in the home invasion robbery and assault was the center of an ongoing investigation into Flood for possible violations of school policy and NCAA regulations for claims that Flood contacting faculty regarding the academic status of a player. Flood defied academic support staff by contacting a professor to attempt to establish the player's eligibility. On September 16, 2015, the university-led investigation determined that Flood's conduct was improper and Barchi fined Flood $50,000 and suspended him for three games. Rutgers associate head coachNorries Wilson coached the three games against Penn State, Kansas, and Michigan State. On January 18, 2019 Alabama hired Flood as Offensive Line Coach.
