AT COLORADO: 2011 (Sr.)—He missed the first eight games of the year after suffering a severe calf strain in fall camp (Aug. 11); he came back to play in four of the final five games of the season, mainly on special teams although he did play the final snap of his last home game against Arizona. Otherwise, he played seven snaps on the field goal/point after touchdown unit on special teams. He had entered the fall tied atop the depth chart at center, and likely would have figured in the mix at guard as well. In the spring, he practiced on a limited basis while completing rehabilitation following surgery to heal a foot injury.
2010 (Jr.)—He suffered a severely sprained foot early in the season opener against Colorado State, an injury that required the surgical implant of screws to help heal; he underwent surgery on Sept. 17 and missed the remainder of the season. He played 12 snaps against CSU, with 10 “plus” plays to grade out at 83.3 percent with one finishing/knockdown block.
2009 (Soph.)—He saw action in one game, against Wyoming, as he was in for one play at the end of the game.
2008 (Fr.-RS)—He saw action in two games, Texas and Missouri, playing 31 total snaps on the year (15 versus the Longhorns, 16 at Mizzou); he had three knockdown blocks total, two against the Tigers, when he graded out to over 80 percent. He added 25 pounds to his frame in the one year since he arrived at Colorado.
2007 (Fr.)—Redshirted; he practiced the entire fall on the offensive line and dressed for nine games, including the Independence Bowl. The coaches selected him as the offensive scout team player of the week for the Miami-Ohio game.
HIGH SCHOOL—A SuperPrep All-Midlands performer, as the publication ranked him the No. 32 overall player in the region (the seventh offensive lineman); Rivals.com ranked him the No. 48 offensive guard in the nation (Scout.com tabbed him No. 70). He was an All-Colorado selection by the Rocky Mountain News and Denver Post as a senior, when he was also first-team All-State (5A) and All-Centennial League. A three-year letterman, he was considered a tenacious blocker in both running and passing situations as he was a key performer for the state’s top-rated offense. He was also a team captain as he manned the center and guard positions, finishing with 90 pancake blocks. He allowed no sacks on the season and helped pave the way for running back Phillip Morelli to average 11.4 yards per carry. He was named second-team all-league as a junior, and was the team’s most improved lineman as a sophomore when he played center and backed up Oklahoma-bound Jesse White at guard. His best game came in his senior season when he recorded six pancake blocks and three touchdown blocks in a 41-38 double overtime win over Douglas County. Under coach Dave Logan, Mullen made it to the state title game all three years Daniels played varsity. Mullen went 13-1 in his senior season, losing to Columbine 13-10 in the title game. His junior team went 11-3 before losing to Douglas County, and his sophomore team finished 13-1 en route to the state title (thus was 37-5 in his prep career). He also played baseball as a freshman, and lettered three times in power lifting, taking third place in state as a junior, finishing behind two seniors.
ACADEMICS— He graduated with a degree in Environmental Science in December 2011. He owned a 3.2 grade point average in high school and was a member of the Honor Roll his sophomore through senior years.
PERSONAL—He was born February 27, 1989 in Denver. His hobbies include most outdoor sports, hunting, fly-fishing, skiing and riding ATVs. He wanted to play for Colorado because it was his dream. His older brother, Brian, lettered four years (2003-06) at offensive guard for the Buffaloes; he started more games (9) as a true freshman than any other player in Colorado history and spent two seasons in the NFL with the Minnesota Vikings.
