Penn State coach Bill O'Brien offered insight into the passing game and a little levity at the Nittany Lions spring game after calling plays over the stadium loudspeakers.

"Don't make me yell at you," he yelled jokingly at a player before calling one play.

Another time, he encouraged fans to start a wave. They made a half-hearted attempt before it fizzled.

Otherwise, the starting quarterback race has been the highlight of spring drills that ended Saturday with the Blue-White scrimmage.

Steven Bench and Tyler Ferguson had their moments and mistakes. O'Brien has said he won't pick a starter until preseason camp in August, after incoming freshman Christian Hackenberg joins the competition.
