New coach, same uncertainty behind center at Penn State.
Bill O'Brien heads into the offseason hoping to narrow the field in the three-man race for the starting quarterback job to two.
The quarterback questions aren't new in Happy Valley. O'Brien's predecessor, the late Joe Paterno, had open competitions for the starting job entering the previous two seasons - and Penn State ended both those campaigns near the bottom of the Big Ten in scoring and total offense.
But there are several new wrinkles this year in a spring already chock-full of changes for the Nittany Lions.
First, O'Brien is installing a new offense based on the high-octane attack he oversaw as offensive coordinator of the New England Patriots. It's taken a while for the skill position players - let alone the quarterbacks - to pick up the schemes just three-plus months after O'Brien was hired for the job.
And O'Brien revealed after Saturday's Blue-White game that he ran just 10 percent of the offensive playbook.
