On my record you will find boxing's longest streak against men, who today are all in the IBHOF. Who am I?
A very good guess! McLarnin's longest streak came at the end of his career, as his last 7 fights were all against future HOFers. But 7 isn't enough to win this category.
Yes, it's hard not to think of Greb in connection with a question like this - but while he had lots of fights against lots of HOFers, he fought so many non-HOFers in between, that he never really got any kind of streak going. So Greb is not our man.
Yes he did, and for a while I thought this was the correct answer. But there's at least one man with 9 in a row. Clue: He was a big man.
