Arreola would be insane to return to the ring against Tua, right after a loss. Arreola needs to take things slow, he's young. Another loss, maybe even a devastating one could break his spirits more than the Vitali loss alone did. He should go back to the gym, fight a bunch of bums to stay busy and work on his conditioning and diet program. Once he's down to 235/40 lbs he should look into fighting other ranked contenders again.
Frequently, I hate qualifiers on occasion. Arreola sucks. He has nothing to beat Tua with. Some people are pointing out his height advantage, but that's only an advantage if you know how to box, which Arreola does not. Arreola doesn't have the power to hurt Tua. Doesn't have tghe skill to box him. The only thing Arreola can do against Tua is get stopped. Tua KO's the big cry baby, and that's why this fight will not happen at this juncture.
I love this fight - wont get made of course for various reasons, but if it did I'd pick Tua KO4 for the reasoins already stated by others in this thread. However I dont like this fight as a Tua fan. KOing Arreola is good and all, but I could see it giving him the momentum to go into a fight against one of the brothers next - especially if he gets Arreola out of there faster than Klit did. Tua needs rounds before he get's in there with either Klit if he's to have a chance, because he needs to be able to push the pace of the fight from strart to finish to beat one of them IMO
