Who got the farthest in boxing with the least amount of legitimate skill or accomplishment?

Conor McGregor.

 

Loved his battles with Dennis Andries.
Just two guy's getting stuck in.

 

Absolutely. No big skill there, but incredible will and determination.

 

Chavez jr must have gotten some good pay days with neither accomplishing anything or having talent. Cooney also in terms of accomplishement, but you can argue he had talent.

 

Keith Mullings - won only 1 fight of his previous 6 fights, yet got a title shot against a jaded Terry Norris and made the most of the opportunity. Retired with a record of 16-8-1.

 

Michael Bentt could fight. He was a top amateur. True, Morrison took hin lightly but Bentt rose to the occasion.

but, yes McNeeley and Nielsen were frauds

 

Buster Douglas

 

Some pretty good contenders in this bracket, Barry Jones is a good one if we are going back a few decades, Audley Harrison too, got some mega paydays from a negligible level of skill as a pro. Out of the current crop, 147 is packed with fighters who fit this bill - Rolly Romero, Ryan Garcia, Lewis Crocker. Connor Eggs Benny is a notable mention, too.
