Did joe louis' last two big fights make him an all time great? His loss to Charles and loss to Marciano?

had he retired before those last two big losses to charles, marciano, you wouldnt consider him an all time great? of course louis is an all time great. marciano didnt have anything left to prove.

jim jeffries retired for the first time at 29 years old. his last loss against jack johnson nearly 6 years later didnt make him an all time great, his 21 fights, (yes only 22 fights in his career) made him an all time great, and if you don't think jeffries is an all time great, there is something wrong. Same with Marciano.
