Like I said I think they want to hold back guys like Evans and Diego. Have you noticed how rare it is to see young guys win Championships? It's a veteran's sport for the most part. There is no point to have guys like Evans and Diego go in and lose to the champions. It's only going to set them back. The best thing they can do is slowly build them up by giving them tougher and tougher opponents.
In terms of his next opponent if it's not Rampage I'd say its either Lambert if he beats Sobral or Jardine. I wouldn't even count out Couture going at him for a retirement match.
You may be right with Babalu vs. Ortiz. I'd love to see him win, because I'm a huge Babalu fan.
I can understand that the UFC doesn't want to have another Quarry/Franklin type fight, but Keith Jardine lost to Stephan Bonnar and Lambert got dominated by Rashad. Prior to his lost, I thought the UFC was grooming Forrest to be the next contender. So for now, I think it depends on if Rampage wins or not. If Rampage wins, he's going to fight Chuck first but if he loses I can see Rashad getting a chance. As for Diego, I can see him get the next shot after Matt Hughes(I'm going under the impression that Hughes had a rematch clause in his contract). And if he fights Koscheck, I don't think it would he would beat Josh as he did in TUF1.
I would also like to see Babalu win, so lets hope this match happens.
