Interesting list. Watson, Manson, and Nurse wouldn't crack the top 20. Maroon is way down the list also.
Remove a few of the guys and add Oleksiak, Morin, Lowry, and the Ritchie brothers. Oleksiak beats up Maroon every time they fight and is 1-1 against Deslauriers. He had the bad showing against Wilson a few years back but I still say he wasn't ready for that fight and Wilson got the quick jump. Lowry will fight anyone and you could argue he beat Reaves in their recent fight. He's had good scraps with Brett Ritchie. The Ritchie brothers win pretty much every fight they are in but they just don't have a huge fight card. Brett Ritchie has beat Tom Wilson and his only close fights are with Lowry. He just throws sledgehammers win he fights.
Reaves is probably still tops based on reputation but he hasn't had a good fight in ages. He needs to have some good heavyweight tilts this year. Lucic is the scariest because you never know if he is going to snap. Wilson scares you more because he might throw a dirty hit but as a fighter he's outside the top 5. MacDermid is top 3 for me.
