After playing behind All-American Jay Leeuwenberg as a true freshman, Stoltenberg became the first center in CU history to start as a redshirt-freshman in 1992. He ended up a four-year starter at the position for the Buffs as the Colorado moved from its option attack to a balanced offense. Stoltenberg blocked for the likes of running back Rashaan Salaam during his 2,074 yards rushing season (1994) and quarterback Kordell Stewart when he threw for 2,299 yards in 1993. Stoltenberg followed in Leeuwenberg's footsteps by being named consensus first-team All-American in 1995, and was first-team all-conference his junior and senior years. After his redshirt-freshman year, Stoltenberg did not allow a quarterback sack (2,260 plays).

Monstrous presence on the Colorado offensive line in the mid-1970s, White played tackle, guard and center for the Buffs. He's believed to be the only player in Big Eight history to letter at all three positions. White was granted an extra year of eligibility after a knee injury in 1976. He moved to center for the 1977 season, and earned first-team All-American honors that year, blocking for a Colorado offense which averaged over 378 yards per game. One of the strongest players in CU history, White benched 465 pounds, while still being able to run 5.1 in the 40. Played one year in the NFL for the Los Angeles Rams, but gained fame as a pro wrestler, calling himself Vader.
