FAYETTEVILLE, Ark. — Texas A&M quarterback Marcel Reed holds the key to an Aggies college football run in 2026. Reed improved as a redshirt sophomore, completing 62% of his passes for 3,169 yards, 25 touchdowns and 12 interceptions. He added another 493 yards and six scores on the ground. But when his team needed him to step up most against Miami at Kyle Field in the opening round of the College Football Playoff, he completely disappeared. One major cause for concern is his lack of consistency as he suffers from mental lapses at critical points despite his overall skillset.
