Iv'e already seen how Marquez superior boxing skill is nullified by someone who can box moving backwards.

If anyone can, check out Marquez' fight with Julian Wheeler.

I know it was a 10th round stoppage but trust me, Wheeler was giving Marquez a bit of a boxing lesson before the ref brought on a pretty horrible premature stoppage.

I don't know if Marquez has fought someone who can fight in reverse gear as well since
