With Yan/Sterling, Moraes/Font and possibly Aldo/Chito booked a TJ/Cody fight for a title shot makes sense.
Dont know what you do with Edgar though assuming No Chin drops to Flyweight and gets that title shot. If he sticks around BW him vs Edgar could work but if his plan and UFC's plan are to fight Fig/Perez winner what does Edgar do? Fight someone down the rankings like Rivera, Cruz or Assuncao?
Thats why I could also see TJ getting a warm up and Edgar/Sandhagen fight for a possible title shot and TJ comes back and fights a Rivera or Munhoz. Might be better to get him two fights before a title shot rather than throwing him right into a number 1 contender fight.
