Here's a break down of regular season "big game" wins and loses over the last two seasons.
08 - 09
Loses: Arizona State (#17), Wake Forest (#6), @UNM, UNLV, @Utah, @UNLV, SDSU (MWC Tourney), and A&M (NCAA Tourney)
Wins: Tulsa, SDSU, @SDSU, Utah, Utah State, UNM
07 - 08
Loses: North Carolina (#1), Michigan State (#10), @Wake Forest, @UNLV, @SDSU, UNLV (MWC Tourney), and A&M (NCAA Tourney)
Wins: Louisville (#6), @UNM, UNM, @Utah, Utah, UNLV, and SDSU (MWC Tourney)
Against ranked opponents we certainly struggle against and typically lose. Against conference teams, we win the "big games" about 50 percent of the time, except for the MWC tourney.
