Personally, I'd swap Ark. St. and JMU ... plus Marshal and ODU.
I see the argument for keeping JMU, somewhat, but the purpose of the challenge is best vs. best so a home and home rematch with Ark. State, with a chance to avenge that OT loss, is my preference. I'm also guessing, If I'm Miami, a game vs. Marshall would hold a lot more interest for multiple reasons than ODU ... as for UMass, as MAC rookies, who cares what team they draw. ODU should suit them just fine.
This looks like matchups were pulled out of a hat with no real thought at competitive pairings. The only teams with legit NET competitive pairings, in my mind, are S. Alabama-Toledo and Troy-Kent.
