Maybe I am the only nut in the room but the Huskers checking in at #4 overall still confuses me. Yes, they play a very easy non conference schedule except for a trip to Blacksburg. Still they replace their quarterback, all of their wide receivers, and a couple starters on the offensive line. Only Missouri returns less starters than Nebraska in the Big 12 from a year ago. I think that speaks volumes. They are replacing almost half of their starting team. We will see but I think Colorado's schedule sets up just as nice. The Buffs moved up one spot in the power rankings from the pre-spring release. 7. Colorado: The Buffaloes remain the Big 12's mystery team and Tyler Hansen's thumb injury only accentuates that uncertainty. New offensive coordinator Eric Kiesau will be taking over this summer. And while he's been around the program for three years, it's still a concern taking the top job. The offense looked fine in the spring game, particularly a bruising rushing game keyed by Darrell Scott and Rodney Stewart. The defensive line remains the biggest question on the other side of the ball and we won't know how that group will play until the season begins. Dan Hawkins confidently picked the Buffaloes to go 10-2 after last season. They'll be better than last season's 5-7, but I'm not sure they will live up to their coach's optimism. February pre-spring ranking: 8. He also names the Buffs' offensive line as the unit with the best collective performance this spring of all Big 12 schools. Pretty impressive considering a few probable starters returning from injury this fall: Best collective performance, offense: After finally getting healthy, Colorado's offensive line dominated throughout the spring. The Buffaloes culminated their development by producing 274 rushing yards and netting nearly 5.5 yards per carry, even when five sacks were factored into the statistics.
