It’s an old-fashioned phrase meant to ward off bad luck when times are good, so it’s natural that Iowa State’s old-school head wrestling coach, Kevin Dresser, often uses it. The Big 12 Championships beckon on Friday and Saturday at the BOK Center in Tulsa, and unlike last season, Dresser’s Cyclones enter the postseason relatively healthy. Dresser’s also fond of the phrase “pep in their step” and his Iowa State grapplers are embodying it in the sport’s most important month.
