DeMulling came to Idaho from Cheney High where he was a three-sport standout in football, basketball and baseball. He made his presence felt immediately at Idaho and earned four All-Big West honors during his playing days (1997-2000).
The four-year starter was a three-time All-Big West first-team selection and he was a part of the 1998 Vandal squad that won the league title and then defeated Southern Mississippi in the Humanitarian Bowl, which was Idaho’s first bowl victory at the D1 level.
DeMulling was drafted in the seventh round with the 220 pick overall in the 2001 draft by the Indianapolis Colts and became a regular starter during the 2002 season. That year, the Colts went 10-6 in Tony Dungy’s first year as coach and lost in the wild-card round of the playoffs. The Colts went 12-4 the following year and lost to New England in the AFC championship game. The Colts again went 12-4 in his final year and lost in the division playoffs.
DeMulling became a free agent following the season and signed with the Detroit Lions where he played for two seasons. The team won a combined eight games in those two seasons. After being signed and then released by the Colts, he signed with Washington in 2007 where he finished his playing career that season.
DeMulling worked for a couple of real estate companies in Indianapolis following retirement and then got into the insurance business. His true passion, however, lies with his community. In 2019, he sold his nice home on seven acres and moved into an impoverished area of downtown Indianapolis to make a positive spiritual impact in the community. He also has been an assistant high school football coach.
DeMulling and his wife, Danielle, have three children: Corinth, Jeremiah, and Grace.
