Mann was primarily the kickoff specialist during his first two years at Texas A&M. During his freshman season, he averaged 63.9 yards on 76 kickoffs, and as a sophomore, he averaged 62.4 yards on 73 kickoffs. He was not the starting punter during his freshman year and only punted the ball twice during the season (two punts for 94 yards, or a 47.0 average). As a sophomore, he did not punt at all and made only one kicking attempt, which came when he missed a 43-yard field goal try in the season-opening 44–45 loss to
UCLA. Following the graduation of veteran punter Shane Tripucka, Mann became the starting punter during the 2018 season, and made an immediate impact on the team. During the
Alabama game, he broke the
NCAA football bowl subdivision single-game record with a 60.8 punting average. The previous record of 60.4 was set in 1983 and matched in 2010. During the
Kentucky game, he recorded an 82-yard punt, which in Texas A&M punt history was the third-longest and longest since 1944.

Pat McAfee. Mann continued to receive recognition for the remainder of his junior season. During the November 2018 game against
University of Alabama at Birmingham, he made his 14th punt of 60 or more yards breaking the NCAA FBS single-season record set in 2005 by former Wake Forest punter
Ryan Plackemeier. Following the regular season, Mann received
first-team all-SEC honors from the league's coaches and the Associated Press and was also named the SEC Special Teams Player of the Year. He picked up
first team All-America honors from the Associated Press (AP),

unanimous All-American from Texas A&M. He also won the
Ray Guy Award as the nation's top collegiate punter. Mann led the nation with his season punting average of 50.98 yards per punt. He broke the single-season punting average record of 50.28 set in 1997 by former LSU punter
Chad Kessler. ==Professional career==
