Yeah, but he's got a reputation in the media and amongst many of the fans that isn't all that conducive to him going down as a beloved character. If he's the best pitcher on an eventual world series champion, or maybe just an NL champ, it would really help. As long as he produces I think Z's emotional nature endears him to Cubs fans more than it diminishes his standing. Anecdotally, my mom who knows nothing about baseball and isn't a native speaker thinks it's "cute" when Z stomps around the mound and mutters to himself. And yeah, if Sosa continues to exist where only circumstantial evidence links him to steroids he'll have his number retired--and he should.
