And that brings the sport to perhaps the biggest loss of UFC 168 -- star power. A mere two weeks after Georges St-Pierre vacated the welterweight title and walked off into the Quebec sunset, perhaps only temporarily but maybe for good, the promotion might have just lost Silva as well. Talk about a 1-2 punch to the gut. (What next, Jonny "Bones" departing for the NFL?) Some will decry these marquee losses in terms of their impact on the bottom line. But of greater impact may be one of aesthetics. The UFC already has lost a true artist in GSP, and if we never again see Silva in the octagon, the promotion will have lost its poet laureate. Who'll be left to create the next masterpiece?
