Just for the sake of setting expectations, let's be clear about how bad ISU really is. They've lost 45 straight road games. While playing in the Big Sky. ISU isn't just a FCS team, they are a particularly bad FCS team.
UConn is not a good team. But my guess is UConn would be favored by 28+ points vs. Idaho State.
Maybe I am a Nancy, but I bring this up because it seems inevitable to me that BYU will win this game by ~14 points, and a lot of hand-wringing will ensue. Either expressly, impliedly or un-consciously some of this hand-wringing will be because Utah curb-stomped the "bad team" they played.
So put me on record now: Idaho State in RES is not at all similar to playing UConn in Connecticut. Yes, BYU should win, but the comparison to Utah's game isn't even apples-to-oranges. It is more like apples-to-iPads.
