I'm not worried about Wilder finding a suitable opponent, there are plenty of them out there if he wanted one.
The problem is he will not pick one. I don't know if it's him, his team or his advisor.
Its like he's floating in the center of a swimming pool, he's not going up or down or side to side. Just setting there, on a huge rubber ducky, pretending he's a professional fighter.
Fighters fight, fighters want to fight, fighters can't wait to prove they are the best. I don't think, deep down inside himself, that Wilder thinks he has what it takes.
What other conclusion can you come to when you have a big, physically sound heavyweight with real punching power, who will not step up.
