dont quite understand why silva goes all the way to watch and doesnt go in the ring and challenge him
Because this was a big trolling move many fell for. Anderson never called GSP, UFC is pushing the fight, fans want to see the fight, but Anderson never been the "bully" LyotoLegion likes to describe. If he would climb to the stage, for sure everything would be in agreement. Those guys are not Tito or Forrest protocol breakers.
Anyway, this is GSP comeback night. Lets not spoil his moment.
