Boxing Records Least likely to be broken...

[ElTerribleMorales]

What do you think are the boxing records in general or for a specific weight class that are least likely to be broken?

Here's a couple I think are pretty safe
Joe Louis' 25 Consecutive Successful Title Defenses at Heavyweight

Wilfredo Benitez's youngest Champion at 17 years old

Mike Tyson youngest heavyweight champion at 20 years old

Evander Holyfield 5 time heavyweight champion

Edwin Valero's 18 consectutive 1st round KO's

I think Marciano's 49-0-0 will be beaten 9as Larry Holmes and even Nicolay Valuev have been within 1 fight of matching it), but I doubt the fighter that beats it ends his career undefeated.

Can you guys think of any others?

The Valero one has already been broken by Tyrone Brunson.

I think the Tyson one can be beat as he was a titlist at 20, I think that is doable again.

given the state of the HW division and seeing how the average fighter in the division is in their 30's i don't really think it'll be broken anytime soon

Being champion at 17 doesn't sound to me like something likely to be beaten, I would personally go with that one.

in the US at least it won't be broken, seeing how you have to at least be 18 to turn pro so no chance in hell they'll become champion at 17
