Yalin Sha vs Sean Soriano could be a set up.
Bisping described Sha as a 'wrestler, highly ranked out of China', and he INSTANTLY closed distance on Culibao, who is a very good fighter with a deceptive record.
Sha dominated the first round, but didn't really bother Culibao, and quickly ran out of energy. Culibao has never been submitted and won't be for a while, he's better than that, and he grew in confidence, but Yalin Sha STILL got him pressed to the cage - that's his MO, that's what he'll try and do against Soriano.
Yalin Sha is a top position guy with a number of submissions and TKO's against weak opposition. It's hard to find too much tape on the guy, but he subbed Georgian Kikadze Bondo, and he's not bad...
Soriano, by contrast, has a major weakness in terms of submissions, and constantly seems to find himself on the ground. He's been submitted by total journeymen (Bruce Boyington sounds like he's made up), and invariably loses with his back on the mat. He gets finished A LOT.
The key question is, is Yalin Sha actually talented enough to be here or not? But as such a one dimensional wrestler, I think he has a really good chance against Soriano, whose kryptonite is... wrestling and submissions.
