We only have video of the tail-end of this idiot's run onto the field, but the tail-end happens to be the best part. The Idiot was met forcefully by Ohio State strength coach Anthony Schlegel, who happened to play linebacker for the Buckeyes in his college days. Schlegel artfully slams the Idiot down to the ground before the Idiot is dragged off the field by security. If you're going to run on to the field, at least make it count.
Update: We put in another video below that has some more lead up to the tackle.
