Full disclosure: after Antonio Rodrigo Nogueira, after BJ Penn, my next favorite jiu jitsu fighter in MMA is Paulo Filho.
Here is a
link to a recent interview with Paulao, who had to pull out of a rematch with Chael Sonnen (see above) due to medical and personal issues. Paulo explains what he has been up to, how his recovery has been, and what is next for him and his career.
