The Big East could use a few big wins this week.The conference that always seems to be trying to fend off critics and prove it deserves to be a BCS automatic qualifier hasn’t done much to bolster its reputation the first three weeks of the season.Big East teams are 1-6 in nonconference games against the other conferences with automatic BCS bids. Add to that Pittsburgh’s loss at Utah, Cincinnati’s loss at Fresno State and Connecticut’s loss at Temple, and Big East teams have yet to produce an impressive victory.They have a chance to turn that around this weekend.On Saturday, Cincinnati (1-2), the two-time defending Big East champion, looks to turn around its first season since Brian Kelly left against No. 7 Oklahoma at Paul Brown Stadium in Cleveland.The Bearcats’ offense has struggled under first-year coach Butch Jones, scoring only 33 points against FBS teams, and it will be missing a key player against the Sooners.
