My gut feeling is he's HOF caliber--but I know of a Baseball Prospectus attempt at a MLE for Cuban players that would leave Linares short of that level. I believe we will get better data from Cuban ball in this time frame, and one way or another someone will figure out a sensible way to evaluate these guys. Until that happens, though, it's best to pass.
I ...... haven't seen MLEs on Cuban players that I have much confidence in. If I could fix those information deficits, I'd be thrilled to talk about where they belong. I'm confident that Linares is the leading player from the Castro(s) era, but I can only rank him on a gut feeling, no more. I don't find that persuasive, and don't see the point unless someone has some MLEs that inspire some confidence.
