If roach is lying does that put the slander of Mayweather Senior in a new light?

Mayweather Senior has repeatedly accused Manny Pacquiao of using steroids. I know this is a topic that few wish to revisit but I am going to because of roach's report of Mayweather's demands. I would have expected roach to be outraged but he seems collected and unperturbed by what would at first appear to be a scandalous maneuver to limit Pacquiao's effective punching (10 ounce gloves) and speed (154). If this turns out to be speculation on roach's part how will that affect your opinion of roach and/or will that make Senior's comments seem less offensive by contrast? Both Senior and roach have lobbed salvos at each other through their associated boxers (even though Senior does not train Floyd anymore, they are still close). So I am left to wonder if this is truth or tit for tat.
