For all the naysayers…
I watched MMA Live on ESPN after Anderson Silva's spectacular knock out of Vitor Belfort with a front kick. Silva credited Seagal for the effectiveness of that technique. I did a quick search for the interview, but couldn't find it. Wouldn't be surprised if it pops up in a few days. To paraphrase, when asked why he threw the kick, he said that although it was a technique that he had always known, he has specifically been working on it with Seagal.
Now, who knows? Maybe the Spider was just trying to indulge Seagal. Maybe he wasn't.
For anyone who didn't see the fight, here is a clip of the end (no guarantee on how long the link will be good).
