I do not expect him to go far at all. Unless he manages to hang around for a decade when the division really deteriorates.
Just watching his last fight now.. He's so slow, and easy to tag... He'll get exposed before he even gets close to world level. If looks could kill he'd be #1, but that's not reality.
He seems to have a valuev type of a chin. And has immense size of course. At least he has Buddy McGirt in his corner.
He'll get schooled by Travis Walker, so that he even doesn't get to the level of Christian Hammer, Kevin Johnson, Garber. However, if his promoters play the cards right, he still can get a shot with someone like Fury, David Haye or Deontay Wilder and have his huge payday.
