Where Does Fireman Jim Flynn rate?

"Flynn was KO'd 26 times. "Can you name me one heavyweight who was KO'd more often?"

Per fight, yes. It is pretty easy. Off Boxrec and Wiki, he seems to have had 168 fights. (check his listed record for his last fight on boxrec)

So 26 KO'ed by in 168 fights--1 per 6.46 fights

Mike Weaver--12 KO'ed by in 60 fights--1 per 5 fights

Lee Oma--17 KO'ed by in 96 fights--1 per 5.64 fights

Charley Powell--8 KO'ed by in 39 fights--1 per 4.87 fights

Alex Miteff--8 KO'ed by in 39 fights--1 per 4.87 fights.

So if Weaver had 168 fights, on the same percentage of getting KO'd, he would have been stopped 34 times. Miteff and Powell 35 times.
Flynn was not that durable, but he wasn't that unique for being stopped. He just had a lot of fights.

If I accept Flynn as having 141 fights, it comes out of a KO in every 5.42 fights, still better than Weaver, Powell, or Miteff.

 

Nine of his stoppage losses came when he was 35 or older,6 when he was nearly 40 or more. Thirteen were to the following;
Langford x3
Coffey x2
Dempsey
Fulton
Dillon
Miske
McCarty
Kaufmann
Montgomery
Miske

 

Excellent break down. Very well put.
