[2] Miller attended Columbine High School in Littleton, Colorado, where he played offensive tackle and defensive end.

On defense, he registered 31 tackles, 20 solo with 12 for losses including five sacks, with 10 hurries, four passes broken up, two fumble recoveries with one forced as a reserve.

He was named Colorado's Gatorade Player of the Year, he earned a host of All-America honors for his senior season, including Parade, USA Today, SuperPrep, Rivals.com, PrepStar and MaxPreps.

Miller was selected to play in the 2007 U. S. Army All-American Bowl in San Antonio, Texas, and he helped the West to a 24-7 win.

In his true freshman year at the University of Colorado Boulder, Miller played in 10 games and started seven, including the 2007 Independence Bowl, at right offensive tackle.

He was granted a medical hardship after missing the bulk of the 2008 season due to injury, thus he picked up an extra year of eligibility.

Miller returned to the field in 2009, and started all 12 games, seven at right guard where he opened the season, and five at right tackle when the line was shuffled for assorted reasons.
