At least three ASU assistants will join Bryan Harsin at Boise State

BOISE, Idaho ( - Boise State head football coach Bryan Harsin announced the addition of three members of his coaching staff, Saturday. Kent Riddle will coach running backs and special teams, Steve Caldwell will coach defensive line and Brian Wilkinson will be the director of football operations.

"Kent Riddle brings great experience coaching running backs and special teams to Boise State," Harsin said. "He has coached running backs before, and one of the things I really like about him is the great examples he gives the players. Kent is also a great recruiter and great person whom I really enjoy working with.

"Steve has great knowledge and passion for the game. He brings a lot of experience to our staff, is a great coach and motivator, and is a top-notch recruiter."

Riddle, who has more than 20 years of experience as an assistant coach, and coached at Boise State from 2001-05, was assistant head coach, tight ends coach and special teams coordinator this past season at Arkansas State.

Caldwell, who coached at Arkansas State this past season, has more than 30 years of coaching experience. He has helped coach his teams to two national championships, including the 1998 Division I-A National Championship at Tennessee, and 16 bowl games.

Wilkinson served as Arkansas State's Assistant Athletic Director for Football Operations this past season, and will bring more than nine years of football operations experience to Boise State.

Riddle previously coached running backs and special teams with the Broncos, coaching alongside Harsin. During his Bronco tenure, Boise State was one of the most accurate kicking units in the country, converting 96.8 percent of PATs (330-of-341) and 73.1 of field goal attempts (68-of-93).

The Broncos also finished ranked in the top 25 nationally in kickoff returns each season, and Boise State's punt return units accomplished the same feat in each of his final four seasons.

Former Bronco kicker Tyler Jones was named an All-American in 2005 under Riddle, and was one of three finalists for the Lou Groza Award that season.

As running backs coach, Boise State produced a 1,000-yard rusher in each of his first three seasons, including two from Brock Forsey and one from David Mikell. Forsey was named Western Athletic Conference Offensive Player of the Year in 2002, rushing for 1,611 yards and a national-best 26 touchdowns.

Following his stint with Boise State, Riddle coached at Colorado from 2006-10, where he coached tight ends and special teams. With the Buffaloes, Riddle coached two All-Americans, including kicker Mason Crosby and punter Matt DiLallo.

He then spent two seasons coaching tight ends and special teams at North Texas (2011-12), where he oversaw the efforts of two all-conference performers. Brelan Chancellor became the first North Texas player to record more than 1,000 kickoff return yards in a season (1,094), and punter Will Atterberry was named all-league in both 2011 and 2012.

Prior to joining the Broncos, Riddle was an assistant coach at Army for six seasons, coaching fullbacks from 1995-98, and then coaching special teams and serving as recruiting coordinator from 1999-2000.

He began his coaching career as a student assistant coach at Oregon State in 1991, and was then a graduate assistant with the Beavers from 1992-94.

Riddle earned his bachelor's degree from Oregon State in 1992 following his playing career as a quarterback for head coach Dave Kragthorpe.

Arkansas averaged 2.85 sacks and 7.31 tackles-for-loss in 2010, ranking ninth-nationally in each statistical category. The Razorbacks ranked 36th-or-better nationally in sacks in each of Caldwell's three seasons.

Caldwell spent the 1995-2008 seasons coaching defensive ends at Tennessee. Over 14 seasons, the Volunteers won the 1998 National Championship, made 13 bowl appearances and finished 10 seasons ranked in the top 25.

Tennessee ranked in the top four amongst Southeastern Conference schools in total defense 10 times, and led the league in rushing three times. In 2008, the Vols ranked third-nationally in total defense (263.5), and in 2005 the team's rushing defense ranked second-nationally (82.5).

Before moving to Tennessee, Caldwell was the co-defensive coordinator at Nevada in 1994, where he helped lead the Wolf Pack to a 9-2 record and the 1994 Big West Conference Championship.

Caldwell began his coaching career at A-State, his alma mater, following his playing career (1974-77). A four-year letterwinner at defensive end and linebacker, he was a graduate assistant from 1978-79, and then coached offensive line as a full-time assistant in 1980.

He moved on to Northwest Mississippi Community College, where he coached offensive line from 1981-84. The school won the NJCAA National Championship in 1982.

He rejoined Arkansas State in 1985 as linebackers coach, and was with the Red Wolves through 1989. The school won back-to-back league championships (1985-86), and made three-straight trips to the NCAA Division I-AA Playoffs from 1985-87.
