They're just trying to carefully build both guys back up where they can take part in big fights again. Khan if carefully matched can maybe be a Floyd opponent in the future and they're hoping for more than one big fight from Broner. But obviously matching them together is going to knock one of them out of the picture so they're not doing it. Broner is supposed to be fighting some lightweight next at 140 and Khan is going to be matched with a relatively credible welter they think he can beat, possibly Collazo.
