Mond entered his freshman year at Texas A&M in 2017 as a backup to Nick Starkel, but took over as the starter after Starkel was injured during the first game of the season against the UCLA Bruins.[5] In his first career start, he completed 12-of-21 passes for 105 yards and a touchdown.[6] Prior to Texas A&M's first game of the NCAA 2018–2019 season, Jimbo Fisher, who was in his first year as Texas A&M's head coach, replacing Kevin Sumlin, announced that Mond would be the starting quarterback for the season opener.[7] Despite an initial feeling that Mond and Nick Starkel would continue to battle for the job after a long competition over the summer,[8] Mond held on to the starting position for the remainder of the season, guiding the Aggies to an 8–4 record and a #19 ranking in the regular season College Football Playoff rankings.[9] The Aggies' season culminated in a historic 74–72 seven-overtime win over Southeastern Conference (SEC) rivalLSU. This game set several records, including the most points ever scored in a game in the FBS era, and tied a handful of other games for the longest college football game of all time with seven overtimes.[10]
Entering the 2019 season, expectations were higher for Mond, though his overall performance failed to meet them. While his pass completion rate improved, his total yards and yards-per-attempt slightly decreased. In the 2020 season, however, he was able to improve with career-highs in pass completion percentage (63.5%) and yards-per-attempt (7.6). The Aggies finished the 2020 season 9–1 and ranked fourth in the final AP Poll.[11] Mond performed at the 2021 Senior Bowl and was named its most valuable player.[12]
He finished his career at Texas A&M as one of three SEC quarterbacks, along with Tim Tebow and Dak Prescott, to record over 9,000 career passing yards with 1,500 rushing yards.[13]
Mond was selected by the Minnesota Vikings in the third round with the 66th overall pick in the 2021 NFL draft.[17][18] He signed his four-year rookie contract with Minnesota on June 15, 2021.[19]
Ahead of the Vikings' Week 17 matchup against the Green Bay Packers, Kirk Cousins was ruled out after testing positive for COVID-19. Head coach Mike Zimmer named Mond the backup to Sean Mannion. Mond's debut came in the fourth quarter after Mannion was being evaluated for an injury. He completed two of three passes for five yards in the 37–10 loss.[20]
On August 30, 2022, Mond was waived by the Vikings.[21][22][23]
Cleveland Browns
On August 31, 2022, Mond was claimed off waivers by the Cleveland Browns.[24] He was released by the Browns on August 24, 2023. However, following the trade of Joshua Dobbs to the Arizona Cardinals, the Browns reclaimed Mond off waivers the following day.[25] Mond was then released a second time as part of final roster cuts on August 29, and re-signed to the practice squad the next day.[26][27] He was subsequently released a third time to make room for P. J. Walker on August 30.[28]
