I'm making this thread not to contest the outcome but to examine what was going on more closely.
Off the bat I want to say that this fight was great by both fighters.
Kos is probably one of the best grapplers to start making it big. His takedown power is probably only matched by the likes of Sherk, Hughes, and Karo (when and if he feels like it). Kos played a wonderful game of survival and knew what the judges wanted and knew what to do to keep himself safe. This is a great tactic for winning fights and by no means does it make him a bad fighter (doing what it takes to win is what it's all about).
Every time Kos tried to stnad with Joslin...Jeff landed some good, solid hits. In fact I think Kos actually has a weak chin...for some of those shots wouldn't have rocked him if he was more solid in the jaw. Kos, seeing/knowing he was unable to stand then proceeded to shoot more often (most often all it took was one to get Jeff down). All but one of them was executed very well. He was able to get a hold of both of Jeff's legs and prevent him from getting a good sprawl & slipping a leg out (when agianst the cage) for a defensive takedown knee.
Jeff was just as impressive as Kos was when it came to both offense and defense. Jeff's stand up was impressive. He had good form, stance, and distance when he was using stand up. On almost all the takedowns Jeff was quick to execute a sprawl. The sprawls were quick but not fast enough and not as good technique wise to be able to break his lags back away from Kos's grip. Many of the takedowns Jeff defended from the center of the ring all the way to the cage.
Once at the cage though, Kos's strength got the upper hand. and the takedowns happened. This is where I was impressed with Jeff the most. A lot of people couldn't see it, but Jeff (in two cases in particular) was using his position on the bottom and shifting his hips to flip Kos. When they were agianst the fence Kos is putting a lot of pressure on the left side of Jeff. It is at this moment that Jeff tries to roll Kos over but was unable because the cage ended up supporting Kos. He makes several attempts but can't get it off....(I think some of it was Kos trying to use the cage although I'm unsure what he was thinking). The second time was when they were in the same position in the middle of the Octagon. Kos feeling the pressure of another roll...picks Jeff up and moves him to the cage (good job on Kos's part). I don't remember off hand which round it was but about 20 seconds before the round was over Jeff was working his legs into a really nice triangle. Watching him work from the bottom like that was wonderful. Jeff did a great job on defense...he was always in full guard and was always working his hips to prevent Kos from either changing position or getting in position for G&P (except for that one time when Kos caught him agianst the fence and he was high up in his guard). To bad the judges don't score points for defensive guard skills.
Although Kos won the fight..I think he actually did the least (except for that one breif moment where he was able to get a few elbows in). Proof of this was that once he slammed Jeff a few times. He actually didn't do much other than takedowns. Proof of his inexperience was toward the end of the fight when Kos caught Jeff in perfect side control and then jumped right back into Jeff's guard instead of using G&P or going for an Arm bar. The match really showed that even those Kos is a great fighter he will need to round out his skills and work on his stand up so that it's ready for times when he is unable to take down his opponent. to be able to beat the likes of Hughes and GSP in a possible title shot in the future.
End note: I want to see Joslin in a few more fights in the UFC. I think if he works on his take down defense a little more he will be able to hang with the best of them and have no problem dealing with wrestlers (body strength and shoots).
