Rank these heavyweight contenders

Kabayel/Parker
Dubois
Anderson

I won't rate Jalalov as he hasn't fought anyone decent thus far, and I'm not willing to buy into another potential Makhmudov or Hrgovic before they've actually proved anything.

As for the rated fighters Kabayel is the best technically and H2H but Parker has the best resume and is the most seasoned. Dubois has the best power and he seems to have found something within himself in his past few fights that might hold him in good stead going forward, but technically I think his ceiling is a bit limited compared to the above two. Anderson is the worst of the bunch and seems to have no real love for boxing, which coupled with his out of the ring issues probably doesn't bode well for his future chances. He might achieve a career similar to someone like Bryant Jennings, but I don't see him moving any higher than that unless his team indulges in some extremely selective matchmaking.
