What we learned from Iowa’s 84-74 victory over Ohio State:

-- The Hawkeyes are for real. Most of us already suspected that anyway. You don’t go 13-3 and have Iowa State and Wisconsin on the ropes in road games without having a pretty good team. But on Sunday they left no doubt, closing out a really good Ohio State team in the final minutes on the Buckeyes’ home floor. No team had shot better than 46 percent from the field against Ohio State this season (Iowa shot 47.5) and no one had scored more than 70 points against the Buckeyes in regulation. It’s apparent now that the Hawkeyes not only will get into the NCAA tournament, but they have a chance to make an extended run in the Big Dance.

-- Head coach Fran McCaffery has a pretty good feel for when to make defensive adjustments. McCaffery twice changed from man-to-man defense to a zone to alter the course of the game. He did it once in the first half when Ohio State appeared to be gaining momentum and again late in the game when OSU had opened a 65-62 lead. The Buckeyes turned the ball over several times after that and Iowa finished the game with a 22-9 run.

-- Aaron Craft may be one of the more overrated players in the Big Ten. Despite the fact that the CBS announcers went on and on about his defensive prowess, all the players he guarded in Sunday’s game – Devyn Marble, Mike Gesell and Josh Oglesby – had good offensive success. Craft finished with six points, six assists, six turnovers and five fouls although it appeared he could have been called for a few more of those than he was.

-- Josh Oglesby really is going to play a pivotal role for the Hawkeyes as the season goes on. Oglesby hit two very timely threes and did a lot of other good things Sunday. He was on the floor for most of the second half while freshman Peter Jok never got off the bench. Although you won't hear McCaffery say it, Iowa’s much-discussed 11-man rotation is now a 10-man rotation.

-- Zach McCabe is in an offensive funk. McCabe’s 0-for-8 shooting effort was the only thing remotely negative to come out of Sunday’s game and it’s not something new. In the past six games, the senior is shooting 19.4 percent from the field (7 for 36) and 6.2 percent from three-point range (1 for 16). He had a couple of wide-open looks Sunday and twice launched airballs.
