Re: Rate Ali versus Ellis
As others have said, it wasn't Ali's most complete or exihilerating performance, but considering the solid credentials Ellis had (especially dominant wins over Martin and Quarry) it has to be one of the more impressive first fights back from a maiden defeat by a heavyweight champion in history.
Certainly a more impressive win than the mismatches Lewis, Tyson, Bowe, Frazier, and Foreman staged to get their legs back after losing for the first time. This is much to Patterson's thrilling revenge win over Ingo or Louis' chilling demolition of Sharkey than any of the others mentioned.
Not Ali's best performance or his biggest scalp, but the context of the win is somewhat impressive because it underscores Ali's amazing competitive drive.
