Alvarez is fine. He's not actively avoiding fighting anyone as far as I know. Just wants Diaz/McGregor winner but seems willing to fight whoever.
Bisping is fine too, the Henderson title shot is understandable considering his status in the sport, the fact that it is probably his retirement fight, history with Bisping, and that there isn't necessarily a clear cut #1 contender in the MW division.
Woodley has a history of avoiding fights for whatever reason and combined with the fact that he is relatively unknown and not a fixture in the sport like Bisping and Alvarez makes him the most annoying champ.
