I bet Joe as well, bit biased as im a fan, but as you guys said he only has a couple of fights left. Many of them are quite young and have a lot of fights left, Mayweaher obviously has a good chance especially if he continues to hand pick opponents.
If I had to put money on it though you can't write off the likes of erdei and valuev, wouldn't bet against them knocking over a few tin cans and retiring like Ottke.
