You would think one of the biggest NFL insiders would not have any free time during the NFL season, but John Clayton always has time to go to a Slayer concert.

By now we have already seen the now famous Sports Center promo with John Clayton chilling in his moms house in between sets and jamming out to Slayer. I will be honest I didn't believe John was a huge fan of Slayer, but I got to admit when I am wrong.Slayer was in Seattle this past weekend and John Clayton was in attendance at the show.

Now John was able to make his way backstage and sang a photo with some of the guys. In an interview last year, lead singer of Slayer Kerry King called the promo awesome. Now if only every time John Clayton came on ESPN we could get some "Raining Blood" in the background.
