Over the past year, USA TODAY Sports has obtained and reviewed contracts and compensation details for more than 130 coaches at Football Bowl Subdivision schools. Here are the five deals that provide the least value for their respective schools, based on compensation, buyout parameters and performance, among other factors.

Kirk Ferentz, Iowa

It’s not just the length of Ferentz’s deal, which runs through Jan. 31, 2026, that makes it problematic; It’s also the bonuses and buyout parameters. If Iowa were to terminate Ferentz's contract without cause Dec. 1, it would owe him an amount in excess of $22.5 million.

In the meantime, his base salary is scheduled to increase by $100,000 every year and every eight-win season will automatically trigger a $500,000 bonus. It's a hefty price to pay for a coach who has led his team to double-figure wins just twice in the last decade.

Kliff Kingsbury, Texas Tech

The Raiders are 28-29 in four-plus seasons under Kingsbury, who will make $3.5 million in 2017 — more than Wisconsin’s Paul Chryst and Virginia Tech’s Justin Fuente, among others. Kingsbury also carries a buyout of nearly $7 million, with no mention in his contract of mitigation or a requirement to offset that buyout with a future salary.

Jim Mora, UCLA

Mora will make $3.55 million in 2017, and his buyout, which is 80% of the remaining guaranteed compensation on his contract, would be about $12.2 million if the Bruins fire him this year. Though UCLA’s football program isn’t floundering by any stretch, it has certainly fallen into mediocrity in recent years, posting a 9-13 record in Pac-12 play and a 16-16 record overall since the beginning of 2015.

Bobby Petrino, Louisville

The Cardinals haven’t finished worse than 8-5 in Petrino’s three full seasons, but they haven’t necessarily lived up to the lofty nature of his contract, either. The 56-year-old Petrino will make $3.93 million this year and has a buyout of more than $13.9 million, with no written requirement that he mitigate or offset that buyout with a future salary. It’s the type of deal befitting an elite coach at an upper-echelon program, and Petrino and Louisville don't fit that mold right now.

Lovie Smith, Illinois

Smith’s buyout — a whopping $16.5 million, which ranks 11th in our database — single-handedly lands him on this list. Though there is an offset clause in Smith’s contract, it states that 59-year-old would need only to make “reasonable ongoing efforts in seeking employment” and would receive the full buyout if he simply remained retired after being fired. It's proved to be a risky commitment to make, given that Smith has posted a 5-14 record and won only two games against Power Five teams so far in his tenure at Illinois.
