Ruiz has fifty pounds and four inches on this little Tua fellow. Size and weight always win...oh wait I have a brain. Tua for the win
Andy (in "shape") would have enough to decision Tua. He has real boxing skills and is tough. Guys like Maskaev and Izon were good enough to hang around with Tua and take rounds off of him. Ruiz would probably see the finish line while ahead.
Tua would love this fight! Ruiz comes right in, throws his best shots and gets hammered in the meantime. Tua by 4.
