From Brett:
According to KTAR in Arizona, Mesa Mayor Scott Smith had some interesting thoughts on the disintegration of the ASU/Cubs plan to share the new facilities being built for the Cubs in Mesa. According to Smith, contrary to ASU’s accusations, it was the University, and not the Cubs, who became unreasonable and difficult to deal with. Smith says that the deal would have cost ASU nothing, was convenient for ASU, and should have been the “perfect situation” for all sides. He was forced to pull out of the talks, he says, because he no longer wanted to spin his wheels as a mediator.
This doesn't surprise me. ASU was along for the ride the whole time. At some point this was going to break down becuase ASU would want more than they were willing to give up.
