Tony Ferguson has come forward, brought the action, and showed exceptional toughness in every single fight so far. He has been making a case for a title shot for a long time, entertaining the fans along the way. He wears his heart on his sleeve, comes to fight every time, and is never in a boring fight.
Despite all this, some fans still refuse to give him the benefit of the doubt when he is negotiating the terms of his next fight. There are so many reasons that he could be refusing to sign this particular contract. All of which make far more sense the "he's ducking Khabib" argument.
Some fans are spoilt, others are delusional. I find it astonishing that so many fans can rapidly come to the conclusion of someone "ducking" someone else, without much logic or evidence behind it.
Also, it is quite normal for fighters to negotiate fight deals in a back n forth manor. It is in their best interest to get the right fight, at the right time, for the right amount of money. This is their JOB.
This is NOT ducking, but rather standard practice.
