I don't think Ancajas to be blamed for being overweight. Ancajas as a boxer needs to follow his camp's planned activities. That includes training, diet, strategy, sparring partner, etc. The boxer has no say on this except for some issues that the boxer is allowed to input. This is also the reason why Ancajas camp got a new nutritionist because probably the previous one messed up.
Nah, they should not play the blaming game, and besides, we don't know what happenned inside, it's everyone's fault, it's safe to think that way, and we should be thinking that they will not allow it to happen again, so most likely Ancajas will have a bounce back win.
