AT COLORADO: This Season (Soph.)-He enters the fall listed second at the 'mike' inside linebacker position. He may not start as CU is stocked at the position, but he will work into the rotation and likely see special teams duty.
2011 (Fr.)-He saw action as a true freshman, playing in 12 games, nine on defense (no starts; he missed the Colorado State game with a hip contusion). He saw just 82 snaps from scrimmage, but recorded 18 tackles, or one for every 4.6 plays which led the team; 13 of the stops were solo. He had a season/career high six tackles (four solo) at Washington, with five the very next week against Oregon (four solo). He also racked up six special team points on the strength of five tackles (one solo, with one of the assists coming inside-the-20).
HIGH SCHOOL-As a senior, he was a PrepStar All-Region selection and SuperPrep All-Midlands team member, the latter ranking him as the No. 58 player in the region and the No. 6 linebacker and No. 8 overall player from Colorado. He was named on the prestigious Tacoma News-Tribune Western 100 list and was one of 12 linebackers on the squad. Scout.com listed him as the No. 32 middle linebacker and Rivals.com ranked him as the No. 35 inside linebacker; he was the top inside linebacker from Colorado by both publications. ESPN ranked him as the No. 65 inside linebacker nationally (the No. 13 player from Colorado). He earned first-team All-Colorado and All-State (5A) honors by the Denver Post and was also named first-team All-Big 6 Conference. He earned second-team All-Centennial League honors as a junior and made the honorable mention squad after his sophomore season as Mullen switched league affiliation prior to his senior season. His senior season he recorded 141 tackles (73 solo) including 11 for losses (five quarterback sacks) to go along with two interceptions, one pass break-up and two fumble recoveries, one of which he returned for a touchdown. As a junior, he totaled 127 tackles (72 solo) with one sack. Between his junior and senior seasons, he was a critical part of a defense that combined for 12 shut outs and 11 more games allowing seven or fewer points in 28 games during that span. Under former CU All-American Dave Logan, Mullen compiled a 40-2 record during his three varsity seasons, winning three Colorado State 5A Championships; that included back-to-back 14-0 seasons and a 33-game winning streak to end his career. He lists his top games as the state championship game from each season: he had nine tackles and a sack in a 37-6 win over Regis in the state final his senior year; that same season, he also had 15 tackles in a 35-0 win over Columbine and had 11 tackles, one sack and two fumble recoveries, returning one for a touchdown, in a 41-24 win over Cherry Creek.
