Your Top Ten All Time MIddleweight Big Punchers?

Such a hard list to make.
Especially for Middleweights.
This division has seem some legendary
punchers that were not considered great,
and in some cases a good fighter.
Zale, Graziano, Carter, Briscoe, "Caveman" Lee
are just a few fighters not great skill wise,
but could put almost any opponent on their ass for
the full 10 count.
Than we have the overrated fighters like McCllean
for instance, he was noted for viscous power , but
didn't ko anyone of note in their primes. The rest were
simply cannon fodder.
Underrated fighters like Sibson and Roldan were extremely
dangerous but rarely get mentioned on any list for hardest
punchers.
