I know I'm on the way back machine, but I'm working on a post for Deadspin and just wondering if you guys know of one. Or has it just vanished into the ether of sports?

I would stake my life that it was Iturbe.

If there are any GW Deadspin posters, you can back me up on this call.

I saw this post and I believe that dunk is in the opening montage at the beginning of all games.  Here is a link that has the video....it's a quick clip and if I counted correctly it's the 7th clip after the montage changes from still pics to videos.

I have unearthed a VHS tape of the game.  Posey takes off from a distance of about the second hash line on the lane, the block being the first.  Iturbe and Yegor receive facials.  Shawnta is then fouled on the other end.

Best part for me is Dave Sims saying "He should shoot it", Shawnta hitting the winner, and in the ensuing celebration, a student section guy "high-stepping" all the way across the floor into the melee.  Hilarious.

GW’s win over avier came minute by minute

1:42: avier’s James Posey ties game with monster dunk over two Colonials. Bilas and Sims can hardly control themselves. “That is the most vicious crush I’ve seen all year!” Sims says.

1:44: Students tell fouled-out avier guard Maurice McAfee to “Sit down!” Meanwhile, Bilas and Sims are still talking about Posey’s dunk. Shawnta buries a three.
