Seems like a step down, to me, but maybe he thinks he will play earlier.
New Mexico doesn't play in the MAC so the schedule is a step up.
Well, if you like losing to Oregon 72-0, and TCU 66-17, Utah 56-14, and Texas Tech 52-17, I suppose that's true. I'm not sure that playing teams where you are so dramatically over-matched is enjoyable for anyone, though.
New Mexico also doesn't win, and doesn't play in bowls, so it becomes a matter of personal preference.
