Good ****. I think his core is looking stronger than I've seen it before. He's flexing obviously, but the way his shoulders round out on the top and his trunk looks thick, he looks well-proportioned (meaning as a boxer should). Previously he'd always looked oddly soft and thin. Maybe he put the weight on better this time.
Why is he fighting Karass? Easy win for Marcos after he got his ass outboxed by Devon. Hopefully, Robert Garcia has sharpened him up a bit.
:yep Seriously, people need to stop confusing being effective in the ring with looking good in the ring. Make Maidana cut his power in half and put him in there with a top fundamentally sound amateur, and he'd still out-land him. Skills can be ugly and instinctual.
