There was discussion of building a Wrigley replica in the northwest suburbs. Of course, the dynamics there were quite different than in Arizona. The Cubs are in a 100-year-old park in a cramped residential neighborhood. They obviously needed to either upgrade Wrigley substantially -- a very difficult project given its age and location -- or build a new home. Chase Field isn't even 20 years old yet. At most, it needs a modest boob job.
