1st off I'd say Taylor had the least to prove he was the most accomplished.
Abraham at least finished the tournament even though he did lose and looked horrible
He made his money and got knocked off but now he can go back down in weight
I would say dirrell came out losing the most. Lost Paydays when he comes back I'm sure he won't be making half of what he would of in the tourney fights, inactivity will hurt him as well. But the most significant thing he lost is dignity and respect.
