How do you rate the Negro League greats when discussing the history of baseball?

I completely exclude Negro Leaguers when talking of this era, the only reason being that I need solid numbers to look at, not incomplete stats and a lot of homespun exaggeration. "I saw Josh Gibson hit a ball 800 feet blindfolded using only a toothpick!" Yeah, OK... Thankfully, people are certainly trying to complete those stats as best as is possible, but still... It's just difficult to look at career stats that were recorded as properly as possible vs. the unfortunate shambles that we've been left with for the Negro Leaguers. It's not fair to those players, but I wasn't there to witness their prowess and have to have something concrete to rely on if I can speak with any accuracy.
