But what about the guys toting the ball?
Last season, 47 running backs topped 1,000 yards, including five from the Big 12.
Here's who will hit quadruple-digit rushing yards in 2012 across the Big 12.
1. Joseph Randle, RB, Oklahoma State: Randle is one of two returning 1,000-yard rushers in the Big 12, and the league's leading returner. He'll do it again as a junior in 2012. He's the best and most experienced weapon in OSU's offensive arsenal, and he'll get plenty of touches with true freshman quarterback Wes Lunt learning the ropes in 2012.
2. Collin Klein, QB, Kansas State: Nobody could stop him in 2011, so why would anyone be able to do it in 2012? Manhattan, Kansas' resident Panzer tank could have stood up and alerted the entire defense to the play for some of his snaps in 2011, and it still wouldn't have mattered. He led the Big 12 in carries last season and he may do it again this year. He'll top 1,000 yards easily. He may throw it better and a little more, but coach Bill Snyder won't get away from the bread and butter of his offense.
3. Malcolm Brown, RB, Texas: Brown will break through a crowded backfield this season and surge ahead of Joe Bergeron and Johnathan Gray to earn his first 1,000-yard season as a sophomore. He'll barely do it, but he'll do it. The carries will be spread out between that trio, but Brown should be the most consistent of the group. The only variable is his health. Brown and Bergeron both had trouble staying healthy in 2011.
4. Waymon James, RB, TCU: Ed Wesley's offseason exit frees up 120 or so carries in the offense, and James will be the man to take a few more and top 1,000 yards. James had 875 yards last year, and TCU will have to throw it more than it did in 2011, but James will hit quadruple digits late in the season.
