2. There's actually some justification for expecting Silva to fight a larger guy but not GSP. a) Silva has already fought twice at LWH, GSP has never fought at MW. b) Silva, unlike GSP, says he wants to do super fights and cement his legacy.
Long story short: Silva made his bed, accept it.
As far as GSP goes, I'm happy to see him defend his title against #1 contenders for as long as he can. Hopefully that includes a Condit rematch in the future with Ellenberger somewhere in between.
