Two former University of Louisville football players have returned to their alma mater to be members of head coach Bobby Petrino's staff.
Kolby Smith, who played under Petrino from 2003-06, will coach the running backs, while former Louisville defensive end L.D. Scott will work with the outside linebackers.
"I'm thrilled for both coaches to be back at their alma maters," Petrino said. "They both played for me while at Louisville and have been coaching with me the last couple of season. Kolby and L.D. are terrific young coaches and recruiters and they will be great additions to our staff and the community."
Smith returns to his alma mater after a stellar playing career at Louisville under Petrino. Sharing the backfield with current Chicago Bears running back Michael Bush, Smith led the Cardinals to a 12-1 record as the main back in 2006. With Bush's season ending early in 2006, Smith stepped in to average more than five yards per carry, scoring seven touchdowns on a team that defeated Wake Forest in the BCS' Orange Bowl.
For his career under Petrino, Smith rushed for over 1,800 yards, averaging nearly six yards per carry, and scored 18 touchdowns on the ground. Smith was also a threat catching the ball out of the backfield in Petrino's offensive system, pulling in 56 passes for over 500 yards and two touchdowns.
Smith returns to the Cardinals' program after spending the 2013 season with Petrino as the running backs' coach at Western Kentucky.
With the Hilltoppers, Smith tutored Antonio Andrews, the nation's top all-purpose player, to a career season on the ground. After setting the school record for rushing yards in a single-season in 2012 with 1,728 yards on 304 carries, Andrews re-set the school mark with 1,730 yards in 2013.
Under Smith's tutelage, WKU running backs combined for 30 of the team's 31 rushing touchdowns in 2013, led by Andrews' career-best 16. Andrews also set a school record for the most 100-yard rushing games in a career (21), in a season (11), and consecutively (11). He generated 125 all-purpose yards in 25 consecutive games, a streak unmatched to within 10 games by any other player in the country.
Smith's running back group also accounted for 724 yards and a pair of touchdowns through the air, showing the same versatility their position coach was known for throughout his career.
Smith's playing career moved on to the NFL level following his time at Louisville, as he was selected in the fifth round of the 2007 NFL Draft by the Kansas City Chiefs. Smith immediately made an impact in his rookie campaign, as he filled the void left by the injured Larry Johnson by rushing for over 400 yards on 112 carries. Smith played in all 16 games in 2007, scoring a pair of touchdowns and earning AFC Offensive Player of the Week honors after rushing for 150 yards on 31 carries against the Raiders.
Smith finished his NFL career in 2010, spending brief periods with the Denver Broncos and the Jacksonville Jaguars.
Following his professional playing career, Smith moved on to Arkansas to serve as the assistant strength and conditioning coach with the Razorbacks for the 2012 season.
A decorated player at Louisville, Scott recently served two seasons as Western Kentucky's defensive ends coach, which included one year under Petrino. Scott also coached with Petrino for two years at Arkansas.
In his first season at WKU, Scott worked with defensive line coach Don Dunn to craft together a lineup that saw much of its unit depart due to graduation. The new lineup improved to a point where it limited its final four conference opponents to just 105 yards in the ground.
Converted linebacker turned defensive end senior Bar'ee Boyd and sophomore Gavin Rocker combined for 7.5 sacks, 15.5 tackles for loss, and eight quarterback hurries on the year, while forcing three fumbles. Boyd also led all defensive linemen with four pass breakups and 40 tackles (29 solo) on the year.
Scott spent the 2011 season as an intern with Arkansas under Petrino working with the defensive tackles, before moving to a graduate assistant role in 2012 working with the defensive line.
As a player, Scott was a four-year letterwinner at Louisville, putting together a 41-tackle season in his senior year of 2009. Scott had at least 20 tackles in each of his final three seasons and played a role in Louisville's 2006 season, when the Cardinals went 12-1 and won the Orange Bowl.
After his stellar collegiate career, Scott played one season in the Canadian Football League with the Winnipeg Blue Bombers in 2010 before starting his coaching career in July 2010, when he worked as the defensive line coach at Seneca High in Louisville.
Scott graduated with a degree in communications from Louisville in 2009.
