Are these athletes on concrete at the 2011 ADCC World Championships?

I took a lot of flack for my comment on Facebook on Saturday when I said, “Why are the ADCC Worlds being hosted on a 16×16 mat?”. Here’s a perfect example why…you have the FINALS of the “World’s Best Grappler 2011 Tournament” grappling on concrete. I hope they are better prepared for 2013, because that was unfortunate for the sport.
