I think Kos would beat him up pretty bad this time. Last time around, he grounded Leben at will, but just didn't know what to do after that. Now, he seems to have developed better ground skills and much more aggression. His sub skills must be ok since he has won most of his fights via submission, but his ground and pound looks pretty good.
Kos....has worked a lot on his standup game and of course his ground game is excellent. Although, Leben could land a good one on his face or something, I would see this fight ending up on the ground and Koscheck bustin out some gNp if not..then maybe he could attempt to do a sub...but Leben will probably squeez out some how . Kos 2nd or 3rd round.
Why do you think the UFC has not tried to make this match. I remember Leban complaining that Josh could olny take him down and hold him there.
I would really like to see this match. Im sure it would be very entertaining.
