Each one of those teams listed is literally better than 90% of the non-con and conference games that we play each year. How do i know this? Based on any metric that you want to look at.
Look at this years average Conference Sagarin Rankings...
MVFC: 133 (low of 39 high of 215)
MAC: 114 (low of 81 high of 194)
Sun Belt:105 (low of 30 high of 174)
Also, the current Sagarin Ratings of the "terrible" schools listed above:
UMass: 221
Liberty: 117
EMich: 109
NM: 140
This years non-conference schedule had Butler(250), ND(149), Delaware(163) and Davis(129)
Our league, while it might be strong for the FCS is still shitty compared to all FBS conferences. If the MVFC went toe to toe with the MAC or Sunbelt our conference would have 2 to 3 wins at most (depending on the matchups). So while some like to throw stones about how bad the lower FBS schools might be they are still collectively light years better than anything that the MVFC trots out each and every week.
Throw in the other P5/G5 games that we could be having that schedule would be FAR superior to anything that we see on a yearly basis. Like i said earlier we have 2 to 3 games annually that are interesting.
