I'm excited to see GSP move up, not excited at all about what Silva is doing. GSP is the only guy testing himself here. He should start with a 5 - 10 guy if he's serious about the move. Nothing super about this fight. Of course Silva wants GSP whether he wins or not. Silva should be fighting Wiedman. Waiting for this "super fight" is just another way for Silva to avoid his obligation as a champion. This may not cancel a card, but it's not much different that Jones. Wiedman actually earned the shot and he's being fucked over.
If Silva vacated 185 I don't believe GSP could move up and be the champion there right away. As skilled as he is, I believe size and strength are two of his greatest assets and he'd lose those. 185 is loaded with huge guys and GSP isn't. The UFC talks about being this global entity, then they should be above gimmicks at this point.
My personal thought are that the people who truly believe in their heart that this fight should happen can play it out everyday in their mom's basement using their action figures.
