Whether an athletic director has been in place for more than 22 years (Jeremy Foley) or just a few weeks (Mack Rhoades), each of the conference’s 14 men with that title have made significant contributions to SEC football.

Here’s a brief history of each of their contributions via football hires, stadium renovation projects and more.

Bill Battle, Alabama: He became the Tide athletic director in March 2013, just after the university announced a new contract for coach Nick Saban, eradicating fears that he would leave for Texas to replace Mack Brown. After recently hiring basketball coach Avery Johnson (and firing Anthony Grant), Battle quipped that he doesn’t plan to stick around for a football coaching search.

Jeff Long, Arkansas: His first football move after becoming athletic director in January 2008 was to hire already-controversial Bobby Petrino. The hire ended in flames, but Arkansas’ football team did win 21 games in a two-season period. Long helped the Razorbacks withstand the fallout from Petrino’s motorcycle crash and subsequent admission of an extramarital affair with a staff member. His decision to retain John L. Smith for ’12 proved disastrous on the field, but allowed the team to conduct a full coaching search and yank Bret Bielema away from Wisconsin rather than picking through leftover options late in the ’12 hiring season. Long got a second raise in 13 months when he was named a finalist for the Texas athletic director position. He also has served as the inaugural chairman for the College Football Playoff selection committee. In ’11, Long guided the approval of a $300 million renovation of the Razorbacks’ athletics facilities.

Jay Jacobs, Auburn: He’s hired two football coaches since becoming the university’s athletic director in 2004, one that didn’t work out and one that looks great so far. After dispatching Tommy Tuberville following a disappointing 2008, Jacobs hired Gene Chizik despite his 5-19 record at Iowa State, his only head coaching experience. Though Chizik won a BCS championship in 2010 with Cam Newton, Auburn fell to 3-9 in ’12, prompting Jacobs to make another switch — this time to Gus Malzahn. Jacobs’ contracts with Under Armour rank as some of the most lucrative in college football history. Some of his many facilities improvements include a $16 million indoor practice facility, building the largest video scoreboard in college football ahead of the 2015 season and piloting the restoration of the Toomer’s Corner oaks.

Jeremy Foley, Florida: The only athletic director in Division I history to oversee multiple national championships in football and basketball, Foley is the senior member of the SEC’s ADs, holding his post since 1992. He’s overseen plenty of capital fundraising, leading to two major expansions of the team’s football stadium, among other things. He got promoted to AD after Steve Spurrier’s tenure was well underway, and didn’t make his first football hire until 2002 — hiring the ill-fated Ron Zook. His second hire, Urban Meyer, won a pair of national titles for the Gators. Since then, he’s hired two more head football coaches in Will Muschamp and now Jim McElwain.

Greg McGarity, Georgia: Mark Richt became the Bulldogs’ head football coach long before McGarity arrived from the University of Florida to become UGA’s AD in September 2010. McGarity gave Richt a two-year contract extension and raise this January. His biggest contribution in terms of facilities is to spearhead the university’s dazzling indoor practice facility, set for construction beginning in January 2016.

Mitch Barnhart, Kentucky: At a school that emphasizes basketball, Barnhart has made a clear, conscious effort to make the Wildcats competitive in football as well. The year after his hiring as AD in 2002, Barnhart hired Rich Brooks as UK’s new football coach. Brooks, of course, started what became a streak of five consecutive bowl appearances in ’07 that stretched into the first year of Joker Phillips’ tenure and included players like receiver Randall Cobb and quarterback Andre’ Woodson. Mark Stoops is Barnhart’s third football coaching hire. He also has backed a $110 million renovation of Commonwealth Stadium that’s currently being completed as well as a campaign to fund a new $45 million football training facility.

Joe Alleva, LSU: He became athletic director in April 2008, just in time to watch coach Les Miles and the Tigers win a BCS national championship that fall. He’s been able to ride Miles’ coaching tenure for his entire stay as athletic director. Under his watch, LSU expanded the South end zone of Tiger Stadium to include a new upper deck and new luxury suites. Alleva also has helped LSU retain Miles as coach through a few occasional rumors, offering the coach a two-year contract extension in 2012.

Scott Stricklin, Mississippi State: He assumed the athletic director’s office in May 2010, one season after the school hired Dan Mullen. Stricklin has ensured that the Bulldogs do everything possible to pour resources into the football program, including a big extension/raise for Mullen (of more than $1 million per year) following the historic ’14 season. Stricklin has overseen a massive fundraising campaign that has allowed the team to build the $25 million Leo W. Seal Jr. Football Complex, as well as a $75 million expansion to Davis Wade Stadium.

Mack Rhoades, Missouri: The SEC’s newest athletic director — we’re talking weeks into the job — Rhoades already has been very active. He’s announced a zero-tolerance behavioral policy, which resulted in the dismissal of starting defensive end Marcus Loud this week. He’s stated that he’d love to see the team resume an on-field rivalry with Kansas someday. He’s worked with Gary Pinkel to resume putting together what should be a major renovation of Faurot Field’s South end zone. He’s also hinted at a complete reorganization of the team’s ticket sales, prioritizing outbound sales tactics designed to raise the attendance at Tigers football games.

Ray Tanner, South Carolina: Installed as AD in August 2012, the former baseball coach enjoyed some beginner’s luck from his new position, as the Gamecocks football team finished the ’12 and ’13 seasons ranked No. 8 and No. 4 in the final Associated Press polls, respectively. He gave Steve Spurrier a raise and a one-year contract extension early in 2014. Tanner also helped oversee a $14.5 million upgrade to the exterior space at Williams-Brice Stadium that should be finished in time for the 2015 season.

Ross Bjork, Ole Miss: Bjork became the youngest power-conference AD in the country in March 2012, a little more than three months after the Rebels hired coach Hugh Freeze. One of the most active, aggressive ADs on social media, Bjork also has increased the school’s athletic budget from $50 million to $92 million. He didn’t launch it, but has assumed control of the Forward Together Campaign designed to renovate Vaught-Hemingway Stadium, helping to raise more than $100 million. Bjork also signed Freeze to a new contract following the historic season, a raise very similar to the one Mississippi State offered to Mullen.

Dave Hart, Tennessee: Hart arrived in Knoxville in September 2011, in the middle of one of the most panned SEC coaching tenures of the BCS era. He decided to relieve football coach Derek Dooley near the end of the 2012 season, overseeing the next hire of Butch Jones. Hart offered Jones a two-year contract extension in December prior to the Vols’ first bowl win since 2008. Though he’s yet to oversee any new major renovations to the football facilities, Hart did help UT add a barber shop to the Anderson Training Center.

Eric Hyman, Texas A&M: Technically, Hyman ushered Texas A&M’s football team into the SEC, accepting the AD job the day before the move became official on July 1, 2012. (Hyman also arrived at South Carolina in ’05 just after the school hired Steve Spurrier.) Johnny Manziel won the Heisman Trophy while playing for the Aggies in ’12, giving Hyman plenty of buzz to launch a $450 million redevelopment of Kyle Field that should be completed this offseason. That’s one of the most massive renovation undertakings in college football history. Hyman also oversaw facilities upgrades while he served as AD at South Carolina.

David Williams II, Vanderbilt: He’s overseen Vanderbilt athletics since 2003, but didn’t officially inherit the AD title until 2012. Derek Mason is the third football coach announced under Williams’ tenure, though the No. 2 guy — James Franklin — is the headliner of Williams II’s football influence. Franklin led the Commodores to three bowl games in three seasons, winning a combined 18 games in ’12 and ’13. As AD, he’s also overseen an extensive refurbishing of Vanderbilt Stadium as well as a multi-purpose $30 million indoor practice facility that football used this spring.
