I don't get an east coast team training in AZ. It was much better when CLE was in Winter Haven.
As I recall, the decision to move (when the FL lease was up) was based on the fact that more teams were in AZ, meaning more scheduling opportunities, and the suspicion was that even more teams would join the westward exodus. I haven't checked the count lately, but one thing can be said, the weather is more reliable in AZ. The Indians were in Winter Haven because they lost their Homestead facility to Hurricane Andrew when it was brand new. And maybe enough teams training out there will placate Las Vegas for a while until a franchise is lured into their web!
