I would also pick Mattysse to win. Not because of recent events with Pacquiao, but Mattysse would be a stylistic problem for Pacquiao, not unlike Morales was in the first fight, except Lucas has more power. Hard to say he wins by KO, but they would both take a beating, Mattysse would just give Pac a worse one.
Pac by UD. He'll dart in and out. Solid footwork and handspeed is always a nightmare for a plodding fighter like LM. But I hope I'm wrong and if I could make the fight happen this weekend I would.
