Yeah, that's why trading him would make sense. The Cubs have a lot of talent in the middle infield in terms of prospects. Russell, Baez, Torres, Alcantara (though he's more of a utility guy), and possibly La Stella (who's finally coming back from injury). Still though, 3 all-star appearances before the age of 25... it's tough to count on the prospects living up to those kinds of expectations even if some of them are potentially elite prospects.
And the rumor is that the Cubs plan to make a strong push for Zobrist in the offseason too.
