Jabbo,
I have some of the fighters you refer to on my ratings list, so it should not be a long wait. Axel Schulz is already done, and my be further back in this thread. You may also go to the Cornerwork site where there may be more of the guys your looking for.

I think Mike "The Bounty" Hunter is there also.

I will soon be doing Adilson Rodriguez, have added Howard Smith to my list, Alexandre Zolkin, Alex Garcia, Martin Everett, David Jaco, Gary Mason, Oliver McCall, Henry Tillman, Jimmy Abbott, Jerry Jones, George Chaplin, Marvin Stinson, Jose Ribalta, to name a few,.....there will be others.
Please keep in mind that these are subjective ratings based on looking at a fighters career opponents, research, playtesting, other variables, input from other members here, and any other info I can garner and at times from my memory. (as a old fart,..57..I remember alot of these guy's...hehe)
I take this information (with alot of playtesting) and try to apply that to TBCB as it exits now. You could just take the ratings off the old game cards and enter that, however, your results in most cases would not mirror the real life results or talent of that fighter due to changes in the TBCB code. At least I believe that to be true.
I must say that I am learning how to rate fighters on the fly. There are many more here "much" more knowledgeable than I at this. I think the ratings I have done so far are fairly close.
I try to be sure a guys Ko's,..rounds fought, style,...ect...ect are as close to his career as I can make them. Not "dead on" but close I hope.
The whole process of doing this has taught me alot abot the game, boxers, and boxing history, and I guess I kind of enjoy doing it, as do many others here.
So if others in the community want to use these ratings thats great, I'll post them for consideration. If not, thats cool.
My project is small compared to what others have in the works.
In any case It's a great game that's only going to get better with the support from the company and developers!
