Last week, Mark Schlabach placed the Sooners at No. 4 in his "way-too-early" top-25 rankings for 2012.
This week, Brian Fremeau from Football Outsiders looks at question marks for each school in Schlabach's top five. He says each team has the ingredients of a potential champion -- historical pedigree, roster loaded with talent, and strong recent success. Here's part of what he had to say about Oklahoma's weakness next season:
Oklahoma's overall defensive efficiency was strong (6th best at forcing three-and-outs), but the Sooners gave up explosive drives on 13 percent of opponent possessions. The departures of Big 12 playmakers at Oklahoma State and Baylor will be helpful, but Oklahoma will need to limit explosive plays to truly be a contender.
