Iowa State miscues make an upset difficult

Iowa State's upset win over Oklahoma State was a near perfect performance, especially in the second half.

The effort has been there again this week for the Cyclones. But so have mistakes, and with them has come a big halftime deficit.

Iowa State trails 23-6 and a few self-inflicted issues made the hole bigger than it needed to be.

On Oklahoma's second-to-last drive, Iowa State dropped an interception in the end zone. The Sooners eventually got a field goal.

But the Cyclones' Jevohn Miller muffed the ensuing kickoff, setting up another field goal that never had to happen.

Oklahoma's first points of the game were set up by a fumble, too.

The Cyclones can't hand Oklahoma opportunities like that to score and expect to spring another huge upset.
