NEWARK, Del. – Marvin Clecidor, a 17-year coaching veteran, has been hired as an assistant football coach at the University of Delaware and will work with the Fightin' Blue Hens' cornerbacks, head coach Ryan Carty announced Wednesday
"We are excited to add Marvin to our staff," Carty said. "His experience and passion will be an asset to our program and student-athletes. Can't wait for him to get started."
Clecidor comes to Newark after spending the past two seasons at Penn as the defensive backs coach. He has coached 28 all-conference selections in his career and four NFL players, including two Super Bowl Champion defensive backs.
"I'm excited to join the University of Delaware staff and the Figthin' Blue Hen family," Clecidor said. "I'm looking forward to bringing energy to this team, building relationships with our players and contributing to a defense that plays fast, physical, and connected."
In two seasons with the Quakers, Clecidor coached two All-Ivy defensive backs. He came to Penn following two seasons as safeties coach and pass game coordinator at Temple.
Clecidor was a member of the Western Michigan coaching staff from 2020-21 as an assistant coach, mentoring the squad's cornerbacks and producing one All-MAC selection. In 2021, the corners flourished under Clecidor's leadership, contributing to a defense that finished 10th in the country in fewest passing yards allowed (186.4) en route to an eight-win campaign and a victory in the Quick Lane Bowl. That same year, the Broncos defense shut down their opponents on third down, allowing a 26.8 percent success rate which ranked second in the FBS.
Clecidor arrived at WMU after spending three seasons at Princeton as the co-defensive coordinator and defensive backs coach from 2017-19. While with the Tigers, he produced 17 All-Ivy selections on the defensive side of the ball, featuring six defensive backs. In 2019, the Tigers posted an 8-2 record and went 5-2 in Ivy League competition. Under his watch, opponents scored just 18.1 points per game (ninth in FCS) and were limited to 113.1 rushing yards per game (12th in FCS). The 2018 campaign was a record breaker for Princeton as it turned in the second unbeaten season in program history at 10-0 and 7-0 in Ivy action. Clecidor helped the Tigers rank among the top 10 nationally in scoring defense (fourth, 13.0 points per game) and total defense (10th, 297.3 yards per game).
Prior to Princeton, Clecidor spent the 2015 and 2016 seasons at William & Mary. With the Tribe, he coached three All-CAA selections, including one of the top FCS defensive backs in DeAndre Houston-Carson, who was the 2015 Colonial Athletic Association (CAA) Co-Defensive Player of the Year and a consensus First Team All-American. Houston-Carson was drafted in the sixth round by the Chicago Bears and played eight games for the Bears during his rookie season. In 2016, W&M led the nation (FCS) in pass defense.
Clecidor joined the William & Mary staff after serving as the secondary coach and director of player development and personnel at Monmouth for three seasons (2012-14). During his tenure with the Hawks, he helped develop one All-Big South player, Mike Basile, who was the 2014 Big South Freshman of the Year and cornerback Tevrin Brandon, a New York Jets' signee.
During the 2011 season, Clecidor worked as a defensive graduate assistant at Rutgers and helped the Scarlet Knights post a 9-4 record, which ended with a win in the New Era Pinstripe Bowl. During his time with Rutgers, he helped mentor two future Super Bowl Champions in First Team All-Big East safety Duron Harmon and Second Team All-Big East cornerback Logan Ryan.
Clecidor's other coaching stops include one-year stints at Wagner (2010) and Wilkes University (2009). At Wagner, he coached cornerbacks and helped develop a pair of all-conference standouts as the Seahawks ranked 15th nationally in pass defense in 2010.
A three-year starter as a defensive back at Lafayette (2005-09), Clecidor helped the Leopards earn back-to-back Patriot League championships in 2005 and 2006. The two-time all-conference selection (2007-08) finished his career with 114 tackles and four interceptions, while he ranked second in the league in pass breakups as a junior.
Clecidor received his bachelor's degree from Lafayette in 2009 and earned an MBA from Wagner in 2012.
