fat boy dc has been talking about cutting to 205 for like 2 yearsAny fight between DC and a top HW is pointless as he's repeatedly stated he wants to cut to 205. He doesn't want anything to do with the HW title and any victory he had against anyone at the top would just be detrimental to the division.
That said, I think Werdum is being saved for the winner of Overeem/Browne.
at this point I wont believe it til he steps on the scales
