That was some spectacular no-gi Judo skills shown by Tim Boetsch at UFC 135- Joe Rogan said it was an Uchi Mata, but it would technically be closer to a Harai Goshi, as it reaps outside, not between the legs. Here's an example of the Uchi Mata Joe was thinking of shown by Karo Parisyan.
Also, on a side note, I sincerely hope Steven Seagal gets hit by the short bus he apparently rides around on: http://www.youtube.com/watch?v=GoADogWK-sI&feature=related
No one cares about your opinion, dude. And Anderson and the rest of Black House don't give a rat's ass either, if you haven't figured it out yet.
