Donald Curry and Joey Archer have been eligible for years. They get priority over all of the above. Once they're out of the way, the rest can trickle on in.
Neither of those guys is on the level as Chavez or Tyson; I can pretty much guarantee those two will get more votes and get in. Archer's pretty borderline anyway, IMO. Outside of beating Dick Tiger (and a super shot Ray Robinson), he didn't really do that much. There are probably 10 other guys on the ballot I'd vote for over Archer. And fwiw Cocoa Kid is a lot more overdue than those two.
Tyson and Chavez are certainties to get in. I think Tszyu will make the HOF at some point but he might have to wait, I wouldn't be surprised if Cocoa Kid, Archer or Curry gets in ahead of him.
Theres fighters on the list that deserved it more than KT. Tyson and Chavez will surely be 1st ballot hall of famers.
