I think this is so funny on a few levels.
I'm really torn on Grantland. Simmons and Klosterman suck. Period. They are so ridiculously impressed with themselves. Dave Eggers, Malcolm Gladwell, Jimmy Kimmel and Mike Schur's involvement also do not bode well.
(NOTE: I appreciate Schur's contributions to American comedy, but I'm not a fan of his sports writing. And his piece on cricket was really hard to sit through, especially since cricket kind of rules. I would have footnoted this, BTW, to keep with the Grantland tradition, if possible.)
However, I really like Rafe Bartholemue (who wrote Pacific Rims, hilarious basketball book) and Davy Rothbart (of Found Magazine fame). The Masked Man from Deadspin writes some decent stuff about wrestling. Everyone else falls flat to me.
Anyways, it's pretty awesome that a very visible writer on a very visible website made a reference to TBS. It's just how they did it that irks me -- it's a nice little reference that the .01% of people reading Grantland will understand. There's no link to anything from there. By doing so, Klosterman's essentially making someone else's work his own clever little joke.
But what's really hilarious -- the whole conceit of Rock, Rot and Rule is to make fun of lazy, hackish, too-cool-for-school professional music writers... LIKE CHUCK KLOSTERMAN. I'm not sure if he's picking that up...
