Jeff Sims and Jumbo Cummings could both bang they're also similar for their troubled background i've heard.
Archie Moore Gerry Cooney David Tua Ron Lyle Earnie Shavers Cleveland Williams Sam Langford Curtis Shepherd Povetkin Wilder (no he was never the real champ)
54 out of 61 total wins. Mostly C listers and a couple of fringe contenders like Poreda, Lasky, and over the hill Heeney. Still an impressive ratio by any measure and he had that lanky build like a Wilder probably got good torque on the end of his punches. Seemed like a top prospect for awhile would like to discover more on him.
