McClellan was a bona fied wrecking machine, he had it all he was a killer in the ring a crazed animal with the desire to obliterate the competition.. He had power, chin, Boxing ability and speed.

Nigel Benn had to literally almost kill him to stop him.

If McClellan was around today he would have destroyed the Miranda's Taylor, Pavlik, Calzaghe, Kessler, Abraham etc.
