I'm in my early 30's right in the demographic of the first X-Games. I mean this as sincerely and as seriously as I can that I hope he didn't shoot himself in the head. He deserves to have his brain studied as much as any NFL star. The wrecks, smashes, and slams he took in his career had to result in multiple concussions. R.I.P. Dave. You're the reason everyone in my neighbor had grind pegs.
I was pretty impressed with Peter, but no more impressed than I once was with Wladimir Klitschko. As Moe alluded to, I'd like to seem him step up in competition a bit after that last outing. The man has power, though.
