It's been fun and encouraging for many Arkansas fans to expect that coach Bobby Petrino will transform the Razorbacks into a wide-open, high-powered offensive team.

One problem with that belief is that Petrino's offensive success as a head coach came when he was the coach at Louisville against Conference USA and Big East teams.

"You are not going to score that many points because of the speed of the defenses, the quality of the players and the coaches," Petrino said. "We just need to score enough to win."

Another problem is that the Razorbacks lost their four best offensive players -- tailbacks Darren McFadden and Felix Jones, fullback Peyton Hillis and receiver Marcus Monk.

Yet another problem is that the only returning quarterback with any game experience, Casey Dick, has a lot to prove as a passer. There are several receivers who have played in games, including Lucas Miller, London Crawford, Reggie Fish and Crosby Tuck, but like Dick, they have to show they can excel in the passing game.

With so many questions at quarterback, running back, fullback, wide receiver, cornerback, safety and middle linebacker, this will be a wide-open spring at Arkansas.

"For players, a change in coaching staffs is good for some and not as good for others," Petrino said. "Some players have to prove themselves again and others get a new start and an opportunity to work without preconceived notions."
