Colby's honestly in the best position for an Usman fight right now and even that's not a good one. Number 1 contender, but already lost recently and decisively. His "work back" to the shot was just beating Tyron, which is nice for the ranking, but AWFUL in the context of Tyron's momentum. Colby vs Leon would end any disputes for a title shot, but that's gonna have a wait to it. They gotta try to book it RIGHT NOW.
Wonderboy is the most interesting challenger, but man these top fighters REALLY should be going through each other to get to the title. I think he needs another win, not just for the sake of building back up his momentum and rankings, but also to get him more work against higher level guys cuz he needs to get his rhythm against the kinda fighter Usman is.
