Eric Studesville

In 2001, Studesville was hired as the New York Giants running backs coach under head coach Jim Fassel. A season prior to Studesville's arrival, the Giants appeared in Super Bowl XXXV, in which they lost to the Baltimore Ravens 7-34. There, he guided running back Tiki Barber to three consecutive 1,000 yard rushing seasons and paved the way for Barber to become one of the best offensive weapons for the Giants in the coming years. In 2002, Barber recorded 1,554 rushing yards which was not only a career high for the running back, but the second-most total in Giants franchise history. Studesville was not retained under new head coach Tom Coughlin.

After a coaching change with the Giants in 2004 he joined the Buffalo Bills coaching staff as the running backs coach under offensive coordinator Tom Clements. The Bills would finish the season 9-7, their last winning record until the 2014 season, by scoring 24.6 points a game, with Bills running backs 13th in the NFL in rushing.[3] Studesville is largely given credit for the emergence of Willis McGahee, who, after recovering from a catastrophic knee injury sustained in college, gained 1297 yards from scrimmage. In 2005, the running game was the main highlight of an otherwise stagnant team led by journeyman Kelly Holcomb and 2nd year quarterback J. P. Losman, as the Bills finished 5-11 while McGahee gained 1,425 yards from scrimmage.[4] In 2006, Mularkey was fired and Dick Jauron was brought on to replace him; Jauron would keep Studesville as the team's running backs coach under offensive coordinator Steve Fairchild. After a pedestrian year for the Bills rushing attack spearheaded by Willis McGahee and Anthony Thomas in 2006 (the same year that Division III Coe College product Fred Jackson was recruited to the Bills by its then-general manager and fellow alum Marv Levy and remained on the practice squad that season), in 2007, the Bills drafted Marshawn Lynch who gained 1299 yards in his rookie season[5] under Studesville's tutelage. 2007 also saw Fred Jackson's call-up from the practice squad and emergence as a threat, as he played in 8 games and gained nearly 500 yards from scrimmage while maintaining a special teams role as well. 2008, under new offensive coordinator Turk Schonert, the Bills offense experienced a renewed commitment to its running backs and Studesville pupils Lynch and Jackson combined for 2,224 yards from scrimmage.[6] 2009 brought about an unsettled year for the Bills offense, as Turk Schonert was fired midway through training camp with former Bills quarterback and quarterbacks coach Alex Van Pelt being appointed in his stead. Studesville's charges saw a reversal of fortunes, as Lynch experienced injuries and off-the-field troubles leading to a suspension,[7] and Fred Jackson led the way with 1,433 yards from scrimmage as they combined for a total of 2,062 between Jackson and Lynch. Head coach Dick Jauron was fired midway through the season and replaced by interim head coach Perry Fewell for the remainder of the season. The entire Bills staff was let go following the 2009 season. Studesville would not be retained under new head coach Chan Gailey.

In January 2010, Studesville was hired by the Denver Broncos as the running backs coach under head coach Josh McDaniels.[8]

On December 6, 2010, following a 3-9 start to the season, coach McDaniels was fired by owner Pat Bowlen and Studesville was named the interim head coach in his place.[9] However, the choice of Studesville to replace McDaniels was viewed by some as a surprise. Studesville held the interim head coaching position for the final four games of the 2010 season, during which the team went 1-3, and Studesville started rookie quarterback Tim Tebow in weeks 15-17. Studesville recorded his first win as a head coach on December 26, 2010, when the Broncos defeated the Houston Texans 24-23, a team led by future Broncos head coach Gary Kubiak.

On February 7, 2016, Studesville was part of the Broncos coaching staff that won Super Bowl 50. In the game, the Broncos defeated the Carolina Panthers by a score of 24–10.[10]

On January 1, 2018, Studesville was released by the Denver Broncos.[11]

Studesville had retained his position as running backs coach under four different head coaches: Josh McDaniels, John Fox, Gary Kubiak, and Vance Joseph.

On January 17, 2018, the Miami Dolphins hired Studesville as running backs coach under head coach Adam Gase, whom Studesville worked alongside at the Denver Broncos from 2010–2014.[12] The team announced on February 8, 2019, that they were retaining Studesville as the team's running backs coach despite the firing of Adam Gase as head coach and the hiring of Brian Flores in that role.[13] Studesville received an additional title of co-offensive coordinator on March 11, 2021.[14] Despite the Dolphins' struggles for much of Studesville's tenure, he has survived 3 coaching changes (Adam Gase, Brian Flores, and Mike McDaniel).
