The quarterbacks: Two of the nation's most exciting quarterbacks in 2012 -- one a decorated senior, one an upstart redshirt freshmen -- will direct their offenses, but in very different ways. Oregon's Marcus Mariota is incredibly fast (he had gains of 86, 77 and 58 yards this season), but his speed comes in handy more as a decoy. The Hawaii native averaged just 8.2 rushing attempts per game this season, and some of those were sacks. He stood out largely as an incredibly efficient passer, completing 69.9 percent of his throws for 2,511 yards, 30 touchdowns and six interceptions. Mariota's 165.36 efficiency ranking was sixth-best nationally. It's not a coincidence that Oregon's rushing offense improved to a Kelly-era high of 323.3 yards per game this season.
Meanwhile Klein finished 15th in efficiency, throwing for nearly the same amount of yards (2,490) but running for an additional 890 yards and 22 touchdowns. He carried at least 12 times in every game, with three 20-plus games. Few defenses have been able to neutralize Klein as a runner, as K-Sate has no hesitation calling his number over and over. He's particularly lethal on third downs: The Wildcats have converted 50.3 percent of them, seventh-best nationally. But Klein's passing regressed over the last three games, when he threw five of his seven interceptions. Oregon coordinator Nick Aliotti loves to blitz, and it will be interesting to see how often he brings pressure on Klein.
