Scrippsnews.com writer Todd Miles does a good job summarizing the quarterback situations in the Pac-10, including several open competitions. USC will be looking to enter the post-Leinart era with either Mark Sanchez or John David Booty. Jeff Tedford will decide between Joe Ayoob, Nate Longshore, and others at Cal. And, Arizona State, coming off a bowl win with their highest pre-season expectaions in a number of years, will choose between two returning quarterbacks that both saw significant action last season in Rudy Carpenter and Sam Keller. With the loss of Leinart, along with Reggie Bush and LenDale White, USC is still the pre-season favorite in the Pac-10, but the conference should be up for grabs with Oregon, California, and UCLA looking to close the gap. A few weeks ago, we here at ITB produced a podcast taking an early look at the Pac-10, examining their returning players and their schedules.
