Manny certainly is a dope battler and a heavyweight. I do agree with @
Kiwi Peewee that another title run (or two) could see him in the right direction. Certainly someone who is note worthy of such an honour.
Though i would like to point out, not every single heavy weight should be a HOF'er. Not saying Manny isn't worthy... i just mean for future reference. If we just give every top tier or old head HOF status, it would water down the prestige of such an honour/title...
