PHOENIX â€” All over the field, Oklahoma should create issues for its Fiesta Bowl opponent, Connecticut. But where UConn could have its greatest trouble this game is dealing with OUâ€™s pass offense. Because competing in the pro set-oriented, run-first Big East, the Huskies have yet to see a passing offense as sophisticated, as up-tempo, as prolific as the one OU will carry into University of Phoenix Stadium on Saturday. â€œThey know what theyâ€™re doing,â€ UConn coach Randy Edsall said Sunday after the Huskies arrived in Phoenix. â€œTheir tempo really gets after you and gives you problems. But they have outstanding players, theyâ€™re well-coached. â€œSo itâ€™s a tremendous challenge, but itâ€™s a challenge weâ€™re looking forward to.â€ Itâ€™s also a challenge unlike anything the Huskies have encountered all year. This isnâ€™t 2008, but the Sooner passing attack has developed into one finely tuned machine. Quarterback Landry Jones enters the bowl season ranked third in the country with 330 passing yards a game and 35 touchdowns. And down the stretch, Jones played his best ball of the season. No longer are the Sooners inflating their passing stats with short bubble screens. In the Big 12 Championship against Nebraska, Jones lit up arguably the nationâ€™s top secondary with 342 passing yards, which included several completed throws downfield. Factor in that Ryan Broyles is an All-American at receiver, and DeMarco Murray is one of the best receiving running backs in the country, and the Huskies will have their hands full, even with the Sooners debuting new offensive coordinator Josh Heupel. â€œLandry Jones is an outstanding quarterback,â€ Edsall said. â€œRyan Broyles, the receiver, is very good. They just have tremendous athletes. ... We know itâ€™s going to be a difficult test, and weâ€™re going to have to play very good, sound, fundamental football to give ourselves an opportunity to win.â€ What makes the test all the more difficult is that UConn has had little experience facing the spread passing attack thatâ€™s now rampant in the Big 12. Remember all the problems OU had defending Air Forceâ€™s triple-option? Same idea. The Huskies have faced the spread this season. But usually against teams (Michigan, West Virginia) that utilize it to get into the quarterback run game. In fact, of UConnâ€™s 2010 opponents, only Cincinnati ranked in the Top 30 nationally in pass offense. Sooner fans saw firsthand that UC had a solid pass offense. But not great. But even against a mediocre collection of passing offenses, UConnâ€™s secondary still struggled. Yes, the Huskies were opportunistic with 19 interceptions. Yes, they improved the second half of the season. But they also finished ranked third-to-last in the Big East in pass defense. Rutgers, owner of the No. 79 pass offense, blitzed UConn with 365 yards through the air on the way to a 27-24 victory in October. Imagine what the nationâ€™s fourth-best pass offense might do. Across the field, the Sooners should give UConn its share of matchup problems. And at the top of that list is OUâ€™s high-octane passing attack.
