For 2013-2019, SEC teams
Alabama played: VT, WV, Wisc, USC, FSU, Louisville, Duke (7-0) all home games except for the VT game
Arkansas played: Rutgers, Texas Tech, Texas Tech, TCU, TCU, Co. St., Co. St. (3-4)
Auburn played: Wash St., Kansas St., Louisville, Clemson, Clemson, Washington, Oregon (5-2) 2 Losses to Clemson
Florida played: Miami/FSU, FSU, FSU, FSU, Michigan/FSU, Co. St./FSU, Miami/FSU (4-7) Lost every game 2013-2017, won both games in 2018 & 2019
uga played: Clemson/GT, Clemson/GT, GT, UNC/GT, ND/GT, GT, ND/GT (9-3)
Kentucky played: Louisville (2-5)
LSU played: TCU, Wisconsin, Syracuse, Wisconsin, Syracuse, Miami, Texas (6-1)
Old Miss played: Texas, FSU, Cal, Texas Tech, Cal (2-3) 2 years with no P5 OOC games
Miss. State played: Oklahoma State, Kansas State, Kansas State (1-2) 4 years with no P5 OOC games
Missouri played: Indiana, Indiana, WV, Purdue, Purdue, WV (3-3) 1 year with no P5 OOC games
USCe played: UNC/Clemson, Clemson, UNC/Clemson, Clemson, NC State/Clemson, Clemson, UNC/Clemson (4-6)
Tennessee played: Oregon, Oklahoma, Oklahoma, VT, GT, WV (2-4) 1 year with no P5 OOC games
Texas A&M played: Arizona St., UCLA, UCLA, Clemson, Clemson (2-3) 2 years with no P5 OOC games
Vanderbilt played: Wake Forest, GT, Kansas St., ND, Purdue (2-3) 2 years with no P5 OOC games
So, from this, Florida, Georgia, and USCe actually schedules multiple contending P5 teams consistently.
Tennessee has scheduled top teams, but hasn't done well.
Arkansas, Florida, Kentucky, Old Miss, Mississippi State, USCe, Tennessee, Texas A&M, and Vanderbilt all have losing P5 OCC records (over half the teams in the league)
Alabama never plays a P5 OOC game away from Tuscaloosa or Atlanta.
Old Miss, Miss St., Texas A&M, and Vanderbilt all have multiple years where they don't have a P5 OOC opponent.
There are many additional conclusions to be drawn from this (both positive and negative for the SEC), but I'm done.
