Usually when heated rivals like the Florida State Seminoles and Miami Hurricanes face off, tempers will flare and people will do foolish things. Maybe have a couple too many drinks and wake up the next morning regretting their actions. This guy is probably one of those individuals:
Credit where credit is due: This guy is not scared. Usually when fans run onto the field at sporting events, they hop onto the field from a remote corner far from the action before being wrangled unceremoniously be security. That's simply not this guy's style. He wanted to be in the middle of the action, and while his judgment seems dulled by excess drink, his aim was not.
It's actually kind of amazing that Shayon Green, number 51 for the Hurricanes, doesn't flatten this guy as he's running onto the field. It looks like he couldn't see him, and he just barely missed tackling the wrong guy.
