DALLAS -- Despite the fact that Oklahoma is again the preseason favorite in the Big 12, the conference has a rather wide-open feel to it in 2012. The additions of West Virginia and TCU, both double-digit-win teams a year ago, provide two additional contenders. Throw in reigning champ Oklahoma State, albeit a weaker version without Justin Blackmon and Brandon Weeden, and the Big 12 includes three 2011 conference champions. That has to be unprecedented.

The reason about half of the league conceivably could win its BCS berth is due in part to question marks for each favorite's cause. Here are the chief concerns of the Big 12's top six contenders, in order of their projected finish from last week's media vote.

Oklahoma Sooners

Concern: Surrendering too many big plays versus pass

The scene became far too familiar for the Sooners and their fans in 2011. At least once a game, and several times against Baylor, the ball would sail over the safety's head and into the arms of a wide-open receiver.
