Providing he gets past the filipino, which I think he will. He should fight caballero to unify the WBO and WBA titles. The winner of that fight would be the clear cut #1 contender for izzy's ring belt, or the guy to take the championship over if vasquez moves up to 126.
he could go straight at 126, get the title and wait for the 122 pounders move up...in that case he would be in position to dictate the terms of the contract
fight either caballero or vasquez, and granted he unifies the sbw belt, move up to 126lbs division and knock out gamboa and linares.
Why 126 when he can make an statement at 122 with Rafa Marquez, Israel Vazquez and Caballero. The 122# division has a lot of talent and can keep the fans happy for the next 2 or 3 years.
