I think Franklin could very well hold his own at 205. He may not be the champion but he does have the skill to compete with the best up there.
This weak chin thing has to go too. The guy has been TKOed once, just once. And I'm pretty sure if he got back into the ring with that guy he would win the rematch. He has never been KOed and yet everyone swears he has a weak chin. Wandy Silva got KOed in 44 seconds, does he have a weak chin? Randy Couture got KTFO twice by Liddell, does he have a weak chin? Until Franklin gets KOed I dont think you can say the guys got a weak chin.
