I think this fight is like 65 / 35 in favor of Liddell, but does this fight seem at all like when Rocky lost to Clubber Lang in Rocky III? Bare with me...
It just seems like Chuck is making appearences (commercials, Blade, etc...) and he hasn't fought for a while. Then they go and schedule a fight after his current fight because they're that sure he can win... It just seems like he's happy and content where he is, and with all this other shit going on (coupled with his increasing years) he might not be improving, which is something he has to do... All the while Babulu is piling up wins and tapping people out all over the place.
It seems like an upset in the making, but as I said if I had to bet (which i wouldn't) I'd take Chuck. However, if Chuck fought Thunderlips he'd get rocked.
