If you're an Iowa fan, go give your laptop a big kiss. If you own a desktop, wrap your arms around it. Mac or PC, it doesn't matter. You don't discriminate.
The Iowa Hawkeyes have moved up two spots to No. 4 in the BCS standings, and they can thank the computers for the bump. Iowa ranks No. 1 in computer average, the result of three quality road victories and a win against No. 20 Arizona that looks better by the day. Despite an average margin of victory of just 8.88 points, Iowa is getting rewarded for a very strong schedule.
The human voters still need some convincing, as Iowa ranks No. 8 in both the Coaches' Poll and Harris Poll. The Hawkeyes really could use some lopsided wins down the stretch, beginning Saturday against Indiana (ESPN, noon ET). It will be interesting to see what happens if both Iowa and No. 3 Texas run the table, as the Longhorns rank higher in the human polls but are fifth in computer average.
Iowa should continue to root for Arizona and Penn State the rest of the way.
Penn State moved up one spot to No. 12 in the BCS standings, while Ohio State advanced two spots to No. 17. Wisconsin, which was No. 21 in last week's standings, was knocked following its bye week.
