What major boxer had the worst chin ever

[Hulk]

Tito Trinidad was not hard to put down. Hard to keep down, but not hard to put there.

[Spicoli]

Michael Moorer often touched

Edwin Rosario,Explosive as any but was buzzed a bit

I read about a guy waaaay back named "Joe Grim".More of a journeyman that was dropped ALOT by some big names.17 times by Jack Johnson and about 8 times by Bob Fitzsimmons.Only counted over for full count 1 time.It was written that "The brain cells were so small that the nerves were dulled".... I know,not a major guy but more of a WTF thing.
