Since Pac's team keeps making excuses I too doubt the fight will happen so the ideal replacements would be in this order: 1. Martinez- I believe he would beat Floyd. 2. Canelo- Young, tough, and packs some serious power. (Not a mental midget like Ortiz.) 3. Cotto- Is really the only other option if the first 2 don't get made, but I would not pay to see it. It would be a boring UD for Floyd.
I agree with poster above. Canelo is huge so he gets a puncher's chance. Cotto is vurnable of getting ko.
