Interesting discussion, guys. I managed to find a ratings list for 1921 put together by mattdonnellon who is a poster here and seems very well informed on old boxing history. Here is his list: Champion--Jack Dempsey 1--Harry Wills 2--Fred Fulton 3--Tommy Gibbons 4--Harry Greb 5--Georges Carpentier 6--Billy Miske 7--Gene Tunney 8--Joe Beckett 9--Bill Brennan Wills is the obvious top contender. Fulton was coming off a bad KO loss to Wills and had earlier been flattened by Dempsey. Miske and Brennan had already had title shots against Dempsey and been KO'd. Tunney? Had he beaten any heavies to this point? My take is perhaps Carpentier should be rated higher, either #2 or #3 behind Wills and possibly Fulton. Given that Dempsey had drawn the color line, Carpentier appears to me to be the best white contender out there. His wins over Billy Wells, Joe Beckett, and Battling Levinsky were KO's and so proved his unquestioned superiority. Gibbons and Greb were a light-heavy and middle whose main "victories" were newspaper decisions in ND bouts. Later events would prove Greb and Gibbons as better than Carpentier, but in 1921 their reputations probably were limited to those reading backwater whistle-stop sports pages. I think this discussion underplayed that Carpentier had KO'd the British Empire champions Wells and Beckett, and the world light-heavyweight champion Levinsky. Those victories being by KO's were I think critical in establishing him as a viable contender over non-punchers who were getting newspaper nods. Now there is the separate issue of Carpentier as an opponent in ATG evaluations of Dempsey. He doesn't rise very high for me. But as a 1921 contender, only Wills was clearly better at that point.
