Heavyweights - Current Ring Magazine Top Ten ...and my own Top Ten (01/10/18)

1. AJ
2. Wilder
3. Fury (actually hard to rank him after his last 2 fights)
4. Ortiz
5. Povetkin
6. Whyte
7. Parker
8. Miller
9. Chisora
10. Breazeale

The other could be ranked top-10 in the near future.
Usyk when he debuts at HW
Jennings if he gets few more decent wins
Pulev if he beats H Fury
H Fury if he beats Pulev
Kownacki
Andy Ruiz if he beats someone decent
Hrgovic after few more wins
Joyce after few more wins

The division is quite interesting, it's full of young prospects as well as seasoned fighters.
