2004 (Sophomore):Â When Brodie Croyle, the Tide's starting quarterback went down with a season-ending knee injury against Western Carolina, Marc closed the game with 5-of-7 passing for 71 yards and one TD. He started the next week at Arkansas, but hit just 6-of-18 for 57 yards and one interception. The next week against South Carolina, he was 9-of-18 for 63 yards and two interceptions. He sustained a lower back injury in that South Carolina game that kept him out of the lineup against Southern Miss and Tennessee. Although he could have played in the remaining games, he did not see further action. With Croyle and Spencer Pennington limited during spring practice, Guillon got most of the reps during 11-on-11 drills. He made huge strides, said Mike Shula. Marc played in 75-of-91 snaps during the spring game, earning the Bart Starr Most Improved Quarterback award following spring practice. 2003 Redshirted. Transfer from University of Miami.
2002 (Freshman):Â Marc signed out of high school with Miami and played in two games as a true freshman. He was 3-of-5 passing for 53 yards and one TD before suffering a shoulder injury that ended his season. He had a 39-yard TD toss against Florida A&M.
