I watched 10 haye fights the last few days & I have no doubt ruiz can win.it's no gimme for David.ruiz is experienced,6-0 in England,in great shape & can go 12 hard rounds.he's durable & has decent power.haye has power & speed but leaves him self vulnerable to counterpunching.he keeps his left hand low & has a suspect chin.he's never been 12 hard rounds,only 2 times he's made it 12 rounds & he landed under 200 punches combined for both fights.if this fight goes late I think ruiz can pull it out.haye needs an early knockout...ruiz been knocked out once.haye doesn't fight well backing up & ruiz may be inside alot hugging & punching.I'm interested to see this fight.
