Maryland's best win is over a 2-6 team, and they've lost to teams that are currently 4-4 and 3-5. OSU is the only team they've played with a winning record. They are currently still overrated from beating a bunch of really bad teams early in the season, but their ranking will continue to fall as they likely don't win another game the rest of the way and miss a bowl game. Yes they are in a better conference, but that doesn't automatically make them way better.
Bowling Green's worst loss is to 6-3 Ohio. Their other losses are to undefeated Liberty, undefeated Michigan, and a 7-2 Miami(OH). That's a combined record of 29-5. And as I said previously, they are likely to continue winning, moving up the rankings, and make a bowl game.
The gap between these two teams is not nearly as big as you want to believe.
It's a shame that arguing your position devolved to calling me delusional and idiotic. Some would say that's poor form...
