It would be an interesting fight, I'd take Berto. Bigger, faster stronger, though Bradley would make him fight with his pressure. I'd rather Bradley stay at 140, a fight with Khan is a must imo and there's JMM, possibly Maidana or an Alexander rematch depending on how they both come back from their losses...I'd much rather he stay put and try and dominate a deep division rather than moving up to WW.
