The Sooners return seven starters to an offense that averaged 36.2 points per game, including All-Big 12 running back Samaje Perine, who set a NCAA single-game record with 427 rushing yards against Kansas.
But defense is Oklahoma's biggest issue, especially with a pass defense that ranked 117th in the country. Last year, the team gave up 276 passing yards per game and nearly 13 yards per completion.
