I saw this discussion going on at another board and thought it was interesting, especially with the recent retirement of #31. In my mind, there is no one likely to get their number retired, but there is one with a realistic chance and one that you could end up making an argument for that wouldn't be laughed out of the room. Zambrano - A fan favorite who has been with the Cubs his entire career. He's slipped off the pasts couple years, of course, but let's say he continues to be productive, if not as productive as he once was. He's currently a three time All Star (might not mean much but it looks pretty) and has finsihed in the top five of Cy Young voting several times, as well as winning a couple of silver sluggers. Let's say he is good for the duration of his contract. That would give him thirteen seasons with the Cubs, none of which were exactly subpar (though some obviously left something to be desired), and most of which were very good. He has the reputation of an ace even if he hasn't pitched like it the last couple of years. I don't think Z will end up getting his number retired, but I think he is the guy that easily has the best chance, and it's not inconceivable at all. If he is productive for the rest of his contract, he will certainly have done a lot more to warrant it than Greg Maddux in his stints with the Cubs. Aramis - He has been with the Cubs since 2003 and has also been a fan favorite ever since. He'd have to produce for the Cubs for more than the duration of his current contract to have any chance at all, though. Even if he is productive for the rest of it, he wouldn't have been with the Cubs for even a decade, and would have played for two other teams. Okay, thoughts?
