I think Fitch will dry hump him for a win. However, if he does beat Fitch I'd like to see him fight Rory Mac or the loser of GSP v Condit. Nick Diaz would be a great test as well.
I don't think they will let him lay on him for 3 rounds in Brazil.
I doubt they would do Silva/Rory. I bet they want them both to be possible contenders. They usually don't put 2 prospects like that in with eachother. That would be a good matchup though.
I think they give Ellenberger to the winner of Fitch/Silva.
