Mayweather + Broner opponent overlap

if Broner beats Malignaggi, two Al Haymon fighters will be champs in the same division, which probably means they'll be fighting the same crop of opponents for as long as May is still in boxing. Does anybody else see this as being potentially problematic? Neither guy will be fighting Top Rank opponents, and I don't think either fighting is going to be venturing up to 154 too often. They could be cutting into each other's list of viable opponents which means we could see more mismatches or have their matches become more infrequent. Or we could have scenarios where a fighter that we want to see Mayweather up against ends up getting fed to Broner instead. Hopefully Broner goes down to 140 after the Malignaggi fight, so the two fighters can fight the best of two divisions instead of just one.
