I don't think Double M's mettle was tested or proven enough at LHW to favor him over any of these guys. As it is, in one of the very few fights at the weight where an opponent offered some resistance (Frankie Swindell), he came away looking a bit chinny IMO.
Agreed 0-3. Saad stops him, Qawi ruins him and Eddie schools him. Above LHW, I'd still pick Eddie, as he'd be without his weight-making issues, so long as he was only 179 or so. Qawi from the first Holyfield fight pastes Moorer so bad he'd wish he was back in with Tua. At least that one was over quickly. Saad is an unknown quantity above 175, so I shan't mention him.
Moorer belongs in a matchup with Prince Charles Williams. That's an excellent fight, and Prince Charles was a level below the Muhammad trio. I would take Moorer to stop Williams late.
