Heavyweight boxers Muhammad Ali and Joe Frazier fought three times in their illustrious careers. ISU wrestler Kyven Gadson and Minnesota’s Scott Schiller are already going on four.

For the fourth time in a little under a year and the third time this season, Gadson, the consensus No. 1 at 197 pounds, will square off against No. 5 Schiller, who was the No. 1 ranked 197 pounder until a loss to Morgan Mcintosh of Penn State on Feb. 9.

The first time the two top-ranked wrestlers met was in the consolation rounds of the 2013 NCAA Championships with Schiller taking home a 6-2 decision victory. On Sunday, Gadson will walk onto the mat boasting a 29-dual match win streak as well as a 20-2 record on the season and it may not be a surprise to learn who those losses came against.

Schiller downed Gadson on Nov. 16, 2013 at the Harold Nichols Open and then against at the finals of the Southern Scuffle on Jan. 1.

“He comes to wrestle every time,” Gadson said of Schiller. “He’s a kid that likes to put his hands on you and keep moving forward … that might have been my downfall the first few matches, maybe I wasn’t ready to go the full seven minutes.”

As far as a rivalry is concerned, Gadson has to hold up his end of the deal.

“He’s a kid that is going to be around and someone I have to beat in order to win matches,” Gadson said. “Right now, it’s not a rivalry. He’s beat me three times and I haven’t beaten him once.”

Despite the headline match at 197 pounds, there are other matches going on.

Minnesota, (13-1, 7-1) the No. 1 team in the nation, will bring eight wrestlers ranked in the top 10 of their respective weight classes, including Schiller and Tony Nelson, the reigning two-time NCAA Champion heavyweight.

“Every single weight class they’re going to challenge,” said ISU coach Kevin Jackson. “They’re the number one team, but there’s opportunities at several weight classes. We’re going to have to compete at each and every weight class to make sure we represent ourselves the best way.”

Last weekend, Iowa State competed in the NWCA National Duals, a tournament won by Minnesota, and were eliminated in the second consolation round with a 1-2 tournament record.

Despite the troublesome record, there were some positives. ISU 125-pounder Earl Hall ended a four-match losing streak and broke out to win all three matches including two against ranked opponents.

“Earl is coming off three wins, so we feel like there is opportunity there,” Jackson said. “Mike Moreno, Kyven Gadson, Tanner Weatherman — you can look up and down the lineup and see those opportunities that are always there. It’s just a matter of competing the right way.”

Action is set to begin at 2 p.m. Sunday at Hilton Coliseum.
