EUGENE, Ore. -- You would think that Oregon quarterback Marcus Mariota returns for his redshirt sophomore season with expectations weighing on him like lead shoulder pads. That could happen when you win the Pac-12 Offensive Player of the Year Award and lead your team to a 12-1 record. You would think that Texas A&M quarterback Johnny Manziel returns for his redshirt sophomore season struggling with the demands of matching his performance last fall. Manziel spent three months transforming from unknown to rock star, picking up the Heisman Trophy and 348,000 Twitter followers along the way.
