Chipper will eventually make the Hall of Fame, despite all of the injuries. His numbers are still very, very good. Like you mentioned, he's a career .300 hitter. And he has 435 HR. Would have hit 500+ easily had it not been for the injuries. I hope he decides that this isn't how he wants to go out, and he rehabs, and comes back to Spring Training for one last season. However, I couldn't blame him if he decides this is it. He's 38. And this is Cox's last season. He could go out knowing he was hitting the ball better than he had all season. At the same time, that reasoning could make him believe he has another year in him. We'll see.
As for Andruw Jones. I have a ball he tossed me once. But I never got him to sign it. Based on how his career has gone lately, I don't think it would be worth anything, anyway. Same with the Andruw card of yours. Guy was destined to be great. But he just didn't have that drive, I guess.
