While I would love to see Silva stay at MW the "big money" fights are not there. Fighting Cote, Okami, Hendo again, Bisping, Marquardt again is not going to net him big paydays. If he plans to stay in the UFC and wants the big PPV cuts he needs to have Joe Silva setup Liddell, Wandy, and Rampage matches.
I know he has said the LHW title is Machida's but he doesnt have to fight for a title. Guys like Liddell and the loser of Wandy/Page are not going to be in the title hunt so those would be safe fights.
