I guess it depends on how you look at Jackson's camp. Is it a training facility or is it a team? If it's a training facility, then anyone who is willing to pay the fee should be able to train there. If it's a team, then it should be more of a "pick and choose" who trains there and who will fight who.
Even as a team, how awesome is it to say you have the #1 and #2 LHW fighters in the world and now they have to fight each other. It's a sport, not a gang war. No reason they can't adjust training schedules so they aren't training at the same time and work towards a great fight.
