Every SEC team has 4 non conference games every season.
Check this year's SEC schedules. Most teams have at least 3 home games; some 4, in their non conference schedules. Most of these opponents are either FCS or G5 schools, who are paying on the road for a "check". Many of the SEC non conference games against other Power schools are at neutral sites, like Tennessee's game with WVU at Charlotte on Sept. 1. UK usually schedules a couple of MAC type opponents and an in state or nearby FCS opponent, like Murray State or EKU. Of course, every other year, their annual game with Louisville is at home. 4 home games, at least 3 gimme wins, and then the mildcats only need 2 or 3 wins in SEC play to be BOWL Eligible!!
Similar situation at Louisville. I believe they agreed to a 2-1 deal with WKU, with 2 games in Louisville. Oh, the WKU "home" game? Well, its not in Bowling Green, but in Nashville, Tennessee.
Get a copy of this year's football schedules. Its the same in EVERY power conference: Big !2, ACC, Big 10, etc., and getting worse every year. Meaning that Marshall's home games with Power opponents like NC State, Louisville, Pitt, VA Tech, Purdue, etc., will be less frequent and harder to schedule for Mike Hamrick as time goes by.
The deck is becoming More Stacked against the non power schools with each passing year, IMO.
