Improved Standup Synodrome, basically when a grappler/wrestler starts to develop a standup game and suddenly thinks it's a good idea to stand and bang with everyone instead of relying on their former strenght.
Werdum's standup was pretty developed by then, TKO'ing Gonzaga (twice) and Vera. JDS is his only loss in 5 fights. Watch the Arlovski fight, Arlovski is one of the best strikers in MMA and he couldn't finish him.
