McGregor announced a long break after the 205 UFC fight so I dont expect him to fight dos Anjos anytime soon. After the break things may have changed a lot. If Nate Diaz fights and loses maybe the interest in a 3rd fight is lost and he fights him, who knows. Things change a lot in 1 year in the fighting game.
Things do change a lot if he is taking a break ,Mcgregor deserves a break as he is one of the most active fighters in the UFC for the past two years and UFC has profited a lot from his presense ,so if he wants to take a break then it is well and fine but the only person who will be pissed about this is going to be Jose Aldo
I do not know how good Tony Ferguson really is but I would assume that this fight will be his first test if he is championship material or not. Sometimes the underdog wins in these kinds of fights because he has more to prove and will fight more ferociously. I speculate Rafael Dos Anjos is looking at this fight as a necessary nuisance and he might not be so motivated.
Tony Ferguson is on 8 fight winning streak and he last lost in 2012 to Michael Johnson,he is a wild fighter who wins most of his fights by his trademark chokes,Dos Anjos will be motivated because the winner of this fight will get the title fight
