The chanted questions seemed rhetorical as the Chico State student body rained down the chants of "Who let the air out?" and "How'd you get here?"  The throng may have been referring to the prank that left four flat tires between two vans which were Midwestern State's transportation to the University Soccer Stadium Saturday morning.  The second-ranked Mustangs, however, had quick and resounding answers for each question.  Junior striker David Freeland scored the first of his three goals just 40 seconds into the match as MSU quickly deflated any Chico State hopes of returning to a Final Four with a convincing 5-0 whipping of the Wildcats in the NCAA Division II national quarterfinals. The Mustangs (19-0-2) are making their second trip to the NCAA Division II Final Four and will face Rollins (Fla.) on Thursday, Dec. 2 on the campus of Bellarmine University in Louisville, Ky.  Catch all the soccer action with live stats or watch the game by going to www.msumustangs.com and follow the link to the NCAA.
