Ryan Day

Ryan Day says his viral golf cart crash sucked all the mojo out of his national championship experience ... joking he felt like he was living out a scene from "Austin Powers" -- and the moment brought him back to reality real quick.

Ty Law is lovin' Ryan Day at Ohio State -- after all, his Wolverines have beaten the coach four straight years -- but he tells TMZ Sports even if he weren't a Michigan alum ... he'd seriously encourage the school to keep the guy on its sidelines.
