6. Kevin Sumlin, Texas A&M
Sumlin has chalked up plays efficiently everywhere he's been. Since his OC days at Oklahoma and then becoming a head coach for the first time at Houston, Sumlin has always had a productive quarterback. Case Keenum was his signal caller in Houston, and Keenum still stands as the NCAA's all-time leader in total passing yards, touchdowns and completions. We all know the job Sumlin recently did with recently drafted 2012 Heisman Trophy winner Johnny Manziel.
Sustaining success is crucial, especially in the SEC, but with the ability to have Texas recruiting, one would think Sumlin will continue to field offensive talent.
5. Mark Richt, Georgia
Richt is a solid coach and fifth best in the conference seems a bit low, but this tells you the depth of the SEC. Richt was one play away from playing for the national championship before losing to Alabama in the 2012 SEC Championship Game, something that has eluded Richt during his time in Athens. Nonetheless, Richt is the owner of the 2002 and 2005 SEC championships.
The playoff era may benefit Richt for finally playing for it all. He certainly would have played for a shot at a national title in 2002 and 2007 if the College Football Playoff was around then.
