NORMAN, Okla. - This was the hard part, in the easiest sort of way.
Iowa State was the last -- well, what's the opposite of hurdle? -- in this month-long drudgery until dessert.
Oklahoma won again Saturday, achieving perfection against the imperfect of the Big 12 world, going 4-0 against Kansas State, Texas Tech, Kansas and now Iowa State.
The dregs are done, but in getting through this gauntlet of graciousness, the Sooners did more than just beat up on some bad teams. They now head to Waco, Texas, playing better than they have all season, and with more confidence, too.
