Both Barker and Macklin unfortunately stack up bad stylistically for Martinez if you're looking for domination or a flashy show. They're both guys that are naturally heavier and try to stay busy to neutralize Sergios speed. Macklin perhaps having an edge with Mcgirt in his corner if you want to push the roy jones similarities. The plan for both guys unfortunately was to remain tight defensively and get Martinez to lead and blitz him when he comes in. Its hard to pick your shots against fighters that do that with some extra weight on you and both of them being rather durable. Sergio is at his best against fighters that lead, present counterpunching opportunities and are not balls to the wall blind flurry type of brawlers. In a division where the pickings may be slim, you have to give it to a guy that picked someone who got jobbed out of title in a different country and gave them a shot. He's also not doing what so many other champions do, pick they guys that are too old (a mosely), too young/green (ortiz), blown up (marquez) or weight drained (cotto) or stylistically flawed (hatton/Margarito) to make themselves pretty. He gives away the weight advantage, many times the height/reach advantage, the constant hometown advantage.. and still finds a way to win. He usually rewards the fans for a few rounds of stinkery with a ko.. who else can you say that about? He doesn't whine or cry all the way to the limo (where he can count his cut of the gate) about how the commentators talk about him.. . He goes in .. does his job, says thank you... and gets involved in causes outside the ring.. despite idiots like merchant that wants everyone to abandon defense and every other skill they practice for the last 2-3 months in favor of swinging big and giving him a rocky moment to babble his 90 proof garbage about while at the mic. Considering he's been jobbed enough times, that anyone else would have thrown a tantrum and quit...I would have to say he deserves more credit for what he's accomplished.
