All good fights, but for me there is no bigger potential fight than Kovalev vs Stevenson. If Pac vs Floyd somehow got made on the same day, the choice wouldn't even be close - Pacman and Pretty Boy would have to wait.
Genna vs Jr has better chances to happen. Both fighters are good draws and both have an excinting style of fighting - Chavez can even block punches with his face. Canelo vs Lara probably will happen if Cotto loses vs Martinez. Molina and Kirkland could be potential opponents for Canelo but I hope not.
