Jackson has a very good chance of winning this fight, just as he did in their previous bouts. Wand is a stronger fighter in the clinch though, which Rampage likes to go for in order to get his slams. When you clinch with a kick boxer you had better be ready to defend knees and elbows b/c they're on their way(listen up Rich Franklin). I think mentally Wand has the edge, as well as athletically. That's not to rule out Page getting the take down and raining elbows for the win, but history has shown us otherwise. Not to mention Page has been a little loopy lately, and is now reiterating himself from their last fight (ie I'm a new man, Jesus saves, etc etc). Wand is also in a better camp IMO(he spars with the guy who just dethroned Page lets not forget) and will most likely bring a better strategy into the ring.
I kinda see this fight being similar to Randy being made to fight Brock on his return to the octagon. Dana is like "Ok you kinda screwed the pooch on that last little stunt of yours, lets see how bad you REALLY want this." Trial by fire if you will.
Wand via "did you really think I wasn't gonna use knees?" tko
