Longest winning streak by a champ - against the SAME opponent?

Yep... but there's a world champion, who can top that!

Clue:
He's a member of the IBHOF - which his opponent is not (nor was he a world champion)

The two met 9 times, with our champion losing the first...
but he sure managed to rebound from that defeat, as he won the last 8 in a row!

 

hh, once again you nailed it... I thought this was a rather difficult question, so well done!

Jamaica kid had an amazing record. He won only 19 of 88 fights... but when you look at the opposition, you realize, that he was matched extremely hard.

He lost to McTigue, Langford, Delaney, twice to Rosenbloom... and besides losing 8 of 9 against Flowers, he went 0-8 against Jeff Smith and 0-10 against Kid Norfolk!
