In 2002, he started all 16 games for the Bills at right guard, a season in which quarterback Drew Bledsoe set 10 team passing records, running back Travis Henry rushed for 1,438 yards, and wide receiver Eric Moulds set a franchise record for receptions with 100.

He was an anchor of the offensive line at the University of Illinois, where he started 45 consecutive games during his career (1997-2000). He was voted second team All-Big Ten in both 1999 and 2000. The Football Writers Association voted him third team All-America after his senior season. He currently works as the recruiting coordinator for the Retired Professional Football Players of Chicago Dollars for Scholars Organization.
