Broner is the bigger, stronger and more versatile fighter of the two so I figure Adrien would win this one by unanimous decision if Yuri fights defensively or even by stoppage or KO if Yuri would gamely trade. Yuri was floored by Filipino Farenas when he slugged with him and had to ride his bicycle to survive the rest of the bout. I think if Broner would tag Yuri, he would not be able to recover as fast and would be in danger of KO/TKO. Tougher guys like Beltran fell when they decided to slug it out with Adrien.
Broner. He has a ton of power down at lightweight and he is the best lightweight in the world. His chin hasn't been tested though but Gamboa certainly isn't the one to test it. Broner by stoppage is the most likey scenario. Gamboa has't been looking impressive lately and isn't active. He's also going to be fading in the next couple of years so Broner is your best shot by a long way.
