Who else out there thinks CHAMPIONS should be ready and willing to defend their title at any time or lose their TITLE......period . Only exception is injury.
Especially once an event is planned.
Would a Gladiator not defend in the Coliseum in front of 50,000 screaming people because different Challenger had spear and shield instead of club and shield and so Gladiator needed more time to train for different opponent.
NO excuses for Jon Jones not fighting any challenger especially when he is being paid handsomely to do just that.
Huh? What happened? 
Agreed, especially if the event has been planned
