Jon Fitch says Nick Diaz is a 'paper champ,' making a rumored fight with Georges St. Pierre at UFC 140 later this year in Montreal perhaps not all that meaningful. Diaz defeated Marius Zaromskis to win the vacant 170-pound Strikeforce title in Dec. 2009. He's won four consecutive fights since that time. Fitch -- a former number one welterweight contender -- is currently on the mend from extensive shoulder surgery. Does he make a good point or is medication affecting his brain?
