Well, as I said about Jonah Lomu, he has trained for quite a while in Muay Thai. I don't know if he has got muich ring experience, but I'm sure he'd train hard going into the fight, and he's got the money to get some good sparring partners. As for "He knows how to handle himself in there", he just doesn't impress me to the extent that I'd say he is anything promising. He's seems as good as a 6'4'' 106kg professional athlete who has been training for a while, is expected to be, but certainly no more. He doesn't seem to have a great deal of power in his punches, and he has a tendancy to back off or headlock too much. Just doesn't seem to have much offense.
