What's the holdup? 5 Pac-12 teams have yet to name a starting QB with season looming

The college football season opens next week and five Pac-12 teams have yet to formally name a starting quarterback.

Oregon State, Washington State, Colorado, Arizona and USC haven't made their starters official.

At 25th-ranked Oregon State, Mike Riley is still trying to decide between Cody Vaz and Sean Mannion. At No. 24 USC, coach Lane Kiffin is looking at both Cody Kessler and Max Wittek.

Arizona coach Rich Rodriguez says he may play two or three in the early games and new Colorado coach Mike MacIntyre is also trying to choose between four candidates.

At Washington State, it appears it's only a matter of time before Connor Halliday gets the nod.
