Actually it makes sense if you're capable of looking at his options objectively. To me the logical option is Luke Rockhold. Having a division with 2 middle weight champions is just dumb. That is like having 2 rulers in a domain, a castle with 2 kings lol wtf.
Weidman should be fighting Vitor or Rashad Evans if he is seriously dropping down to mw. A win over either guy would definitely put him on the map even with casual fans.
Best Fighter on the planet.
