I'd favor him over Werdum. Cains another story.
The truly incredible thing about JDS was he barely took ANY damage before the second Cain fight.....and he fought a lot of top level fighters.
This is a guy that stood with Shane Carwin for 3 rounds and was barely touched.
Bu then the second Cain fight happened, and JDS has been taking massive damage ever since.
Crazy thing is if GSP didn't exist, Fitch could have been the longtime dominant WW champ.
