Hughes lost his title and fought Lytle. To set him up for an immediate title shot (even though he asked for Diego) The UFC is known to lay out a red carpet for title contenders to get the big pay day in the end. The last thing they want is any big name to lose twice.
But then there's GSP-Kos and Fitch-Sanchez, risks there. I guess in the lack WW title fights they are putting top talent against each other?

How profound. Whereas in the LHW they can take their time.
