I don't see it going different from the last fight. Babalu is still the same fighter as he was at UFC 40 except hes gotten better at striking, takedowns, and submissions thats about it, hes still the same just more dominant and hasn't faught anyone like Chuck yet. He will try to take Chuck down but will be striked in the face and eventually TKO'd. I can picture this fight going the same way Horn and Liddell went.
At UFC 19 where Chuck lost I don't think it was submission because he didn't tap he just fell unconcious therefore the referee stopped it. He was badly hurt and should have tapped out. I don't know, the last time I saw that fight was a long time ago.
