Does it look like Spence is still not confident to face his fears? So he is continuing to buy some time to make Crawford older and more inactive. Years of ducking and avoiding the boogeyman.
Crawford is maybe older but he is too far from 40 years old. I think that the delaying tactic is not effective as Crawford will not wait forever for a fighter that is not interested in fighting him, he will certainly schedule a fight with a challenger so he will be active.
