It was a very good weekend for Strikeforce, and I'm not talking about the Challengers card they put on Friday night.
No, I'm talking about the success that two Strikeforce heavyweights -- Alistair Overeem and Fabricio Werdum -- had in a couple of competitions outside mixed martial arts.
Overeem beat Peter Aerts at the K-1 World Grand Prix 2009 in Seoul, advancing to the Final 8 of the world's foremost kickboxing organization. Werdum won the heavyweight title at ADCC 2009, the biggest no-gi grappling competition in the world.
