IMO, he didn't seem like Le Banner of old. I think his left arm is still giving him issues and Botha got the TKO because Le Banner couldn't answer fight the extension round. Apparently he had to go see a doctor straight after the fight.
Also Sefo seems to be in great form, especially since he lost all that weight and only weight 100Kg flat now. Personally I'm hoping for a 98Kg Ray to come in to the finals, like the Sugarfoot Sefo of old, and take the crown this year.
