I like the kind of crossroads matchups which tell you who's good, rather than the kind which tell you which fighter is over the hill. This fight is one of the former.. Fox lost to the two truly good fighters he faced, Demetrius Andrade and Liam Williams, but has handled everyone else. Morrell has looked very impressive since turning pro and has a couple of nice wins. This should be interesting.
For a guy in his SIXTH fight, this is a good opponent for Morrell. Fox is an awkward, rangy opponent who you only/ beat if you're a top guy.
