14 NFL teams have Fieldturf, 18 have natural grass. Colleges: Arizona, Oregon, Wisconsin, Louisville, Syracuse, Kentucky, Houston, Texas, Missouri, Cincy, Ole Miss, Washington, Texas Tech, Iowa, Washington State, Nebraska, Michigan, Navy, West Virginia, Oregon State, Rice, Colorado State......just to name a few. More and more school systems in TN are getting fieldturf as well. I hope this helps in your argument.
