In retrospect that somewhat controversial loss wasn't a further slide into mediocrity, it was a loss to the champ. It was a closer fight than the Rockhold fight, so why not give it to him? Looking at Silva, he looks bigger and stronger and faster than all his opponents. Recently, he's looked like he can't pull the trigger, and can't bring himself to engage. When he does throw with intent, it seems to surprise his opponents as to how strong and quick he still is.
I guess the reasonable fights to make are:
Bisping v Rockhold 3
Bisping v Weidman
Rockhold v Weidman 2
Bisping v Jacare
Bisping v Silva
I don't think Silva gives Rockhold a good fight with current Silva and motivated comeback Rockhold, so let's stay away from that.
