As a significant fight, one of the Guys had lost one. After the Fight, they had both lost one , great Fight. I realised after reading, that you had missed a Big one , you hadnt

How can ANYONE forget Larry Holmes vs. Gerry Cooney

[mrbig1]

I was 15 at the time of the Frazier vs Ali 1. Biggest fight in my lifetime by far.

[CutMeMick]

Just to clarify one thing that the original rough draft I have on my Desktop had well over 150 fights between 2 undefeated fighters. I just had to cut it off somewhere or else the list would deminish in significance of the fight. I will admit though in retrospect I'd leave out Narvaez-Whitfield as well as Thurman-Chaves.

Pure quality stuff Mick! I'd exclude Alexander vs Bradley on the grounds of wanting to keep my last meal down ha. Maybe toss in a Jeff Chandler vs Julian Solis though not 'huge'. A Yuh Myung-woo vs Leo Gamez...division record setter against a guy who would become a 4 division champ you hardly hear of, if at all. Paul Gonzalez in only his 5th fight beating an undefeated and future division great in Orlando Canizales? Jeremy Williams vs Danell nicholson, ok I need a slap . Hey..wish we saw undefeated American heavys meet that early NOW.

@Spicoli
Good call on all of those Spicoli... I didn't have Chandler-Solis in my original rough draft. Thanks. LMAO at Williams-Nicholson.

Kennedy McKinney 21-0-1 vs Welcome Ncita 32-0
And it didn't get much bigger than
Sven Ottke 24-0 vs Anthony Mundine 10-0
If you included Thurman-Chaves you can include
Paul Williams 29-0 vs Walter Matthysse 25-0
Dmitry Pirog 16-0 vs Daniel Jacobs 20-0

@Violent Demise I agree and as I said in my comment at the top. I had so many fights I just cut off the list right there for some reason... I'd def. see one or two that aren't as significant as others I see on the list that I have.

Great list Mick. If Mathysse wasn't robbed against Judah and Alexander, Garcia vs Mathysse would be a notable one on there

@gest12645 Thanks...

May I propose: Leonard Dorin (21-0-0) vs. Paul Spadafora (36-0-0) , IBF & WBA bout unification?

@iwng100 noted... Again I just cut the list off so it didn't make the cut. Good call on it.

DeGale v Groves.
Basically a fight between 2 future world champions.

@Vendettos noted but didn't make cut...

Chris John (47-0-2) vs. Chonlatarn Piriyapinyo (44-0-0)
91 combined wins.

@toe2toe noted but didn't make the cut... He also has one vs. Enoki whom I thought would give John a good fight.

@Memphis well played sir...

How can ANYONE forget Larry Holmes vs. Gerry Cooney

@ykdadamaja it's not that I forgot again it's that I cut the list off...

I was 15 at the time of the Frazier vs Ali 1. Biggest fight in my lifetime by far.

@mrbig1 I think it's general sensus that Ali-Frazier 1 is the most significant fight in the history of the sport.

Marty Servo vs. Ray Robinson

Love your list.
First.... 'cause it's very good.
Second.... 'cause it's got my boy in there four times.

Of course..... it should've been five. Oba Carr was 32-0 when Trinidad TKO'ed him.
