That's a tricky 1 Majesty because alot of fighters write themselves off. David Tua was never the same after Lewis even though he had a couple of good knockouts afterwards but he never really had that spark again even though he was given tons of opportunities. Calvin Brock had a couple of hiccups after Vlad but he couldn't get it together again. Maskaev, Rahman, Ruiz, Holyfield, Barrett and Mccline have used up their 9 lives and then some in the Heavyweights but are given numerous chances.
