Maybe hes is still not confident in his conditioning for 12 rounds and paces himself too carefully. Anyway he is still winning the rounds and will be hard to beat on points...
Something like this probably. I think he values his movement very much and don't want his legs to slow down.
You guys are forgetting something here. Rigo is just starting to adapt to the pro game ( only 8 pro fights fighting Ramos ). Rigo has always been a counterpuncher throughout his entire amateur career. Rigo is not a wrecking machine, he is a masterful boxer. Rigo hadn't fought in 10 months so I am sure that he wanted to get some good rounds in his favor. I am sure that as he gets more and more confident that he will become more aggressive and finish his opponents more early.
After 1st rd Ramos got in a bike and was reluctant to exchange. I'm sure Rigo knew about shimoda fight and didn't want to be careless against someone with a punch. It's why took 4 rds to land the killing flurry. Could have him finish the fight in 2 rds? Maybe, but taking risks in a world title fight that u r dominating sounds a lit stupid to me
