Toquinho is a bad guy, i hate him, he injured Avellan's knee on one his leg locks and they almost brawled.
Excerpt from one blog about ADCC 2011:
"His match with David Avellan resulted in one of the most gruesome knee-bars of all time when after already popping Avellanâ??s knee multiple times after wrenching on a heelhook after the referee tried to stop the match, the Brazilian tree stump almost came to blows with Avellan before he torqued Avellanâ??s knee again leading to the American being carried off the mat."
The referee stupidly reset them when Palhares had the sub on, sub can't take place off the mat (but a certain amount of grappling could). They were reset in the posistion and Palhares just went for it. Galvao was outstanding too, technical and solid. Interestingly most of the sub wins were leg locks.
Sadly for British fighters they all got knocked out in the 1st round, including the highly touted Dan strauss, he was unlucky drawing Calasans in the 1st.
