I think the new UFC should stick to the old UFC's model some what...look at the long term of their company. These money fights are turning divisions into roadblocks and paper champs for the top fighters in their respective (FW, LW, MW and possibly WW) divisions.
Pick a division, stay there. Dominate, then test the waters in a different weight class.
I understand that the new ownership is trying to generate as much revenue as they can right now, and realize that Michael B. is probably the easiest of all match ups for GSP for the MW title, but come on. There is no way GSP stays at MW.
