I think the reality is even lamer than that. The management team at WME-IMG has to pull certain numbers as profit benchmarks for the calendar year 2017 to get bonuses from their financial backers and debt holders- something that got a lot of press at the beginning of the year. UFC 219 occurs on December 30th, and represents their last chance to have another good selling card. So with Conor negotiations pending and time running out, Ronda no longer fighting, Jones suspended, and GSP having just fought they are trying to come up with a name to sell PPVs regardless of whether it makes sense rankings wise. Enter Nate and the need to create a "big fight" to motivate him and justify paying him a bunch of money and PPV points. It's all about the short term right now like when the sales manager of a car dealership who will get a big performance bonus if he sells x number of cars in the calendar year but gets no bonus or peanuts for a bonus if he sells x minus 1 car by 11:59 PM on December 31st. It create a perverse incentive for short term decision making over long term thinking of what is best for the company or the sport.
