If you watch ESPN and are a fan of the NFL then you most likely have heard of John Clayton. If you haven’t heard of Clayton, he is the “goto” guy when it comes to breaking down the league for ESPN. ESPN released a new “This Is ESPN” commercial today featuring Clayton. This definitely gives the Matthew Stafford commercial a run for its money. In this commercial, Clayton is shown doing an interview on ESPN and when it’s cut he really lets his hair down. Who knew he was a fan of Slayer?
