It seems Iowa St's really good defensive efforts come with the offense making at least some shots.
There is very much a correlation between a lack of confidence on offense, and lack of effort of defense.
And it's super hard to just keep grinding against a team that's that much better everywhere to start and has a great night on their own.
Pretty sure that was ISU's worst B12 tourney margin of loss since Cato and Co. got rung up by KU in '97.
