probably the last 20-30 years....and it's not like any of those teams have been powerhouses, generally speaking. Mizzou has been down forever and so has Wake until recently. I'm sure when you scheduled those games, your AD would have never thought those teams would be up and coming when your time came to play.
Here's a list of your OOC opponents the last 10+ years or so...
2009 - Memphis, SELA, UAB, Northern Arizona
2008 - Memphis, Wake Forest, Samford, ULM
2007 - Memphis, Mizzou, La Tech, Northwestern State
2006 - Memphis, Mizzou, Wake Forest, Northwestern State
2005 - Memphis, Wyoming, The Citadel
2004 - Memphis, Wyoming, Arkansas State
2003 - Memphis, ULM, Texas Tech, Arkansas State
2002 - ULM, Memphis, Texas Tech, Arkansas State
2001 - Murray State, Arkansas State, ULM
2000 - Tulane, Arkansas State, UNLV
1999 - Memphis, Arkansas State, Tulane
That's as far as I care to spend time on looking this **** up, but y'all have always scheduled this way. And to boot, before you were forced to play a Division opponent in the SEC, you scheduled the bottom-feeders of the SEC on a regular basis as well. Hardly ever played Bama and have pretty much always had Vandy on the schedule. Your history pretty much mirrors your past season. You beat no one and go to a bowl game. So very impressive.
