If I was the NCAA I'd move the first 4 and Cleveland region to states that will allow fans. If I'm Chicago, Detroit, Indy somewhere else in the Midwest I'd be looking to step in.
For what it's worth from other tweets by the Gov. Ohio has had only 3 people test positive 15 under investigation and 14 tested negative. Funny thing is schools, churches, movie theaters, malls, etc. can still run business as usual in Ohio.
Also lucky for Iowa with top 4 seeds playing in regions close to home Cleveland almost a lock for Dayton and Michigan St. and the 3 other teams in their bracket will be heading there. As long as Iowa stays off 8/9 seed we should be fine.
