Fans of the Oakland A’s are still trying to make sense of the bombshell announcement earlier this month that the team has entered an agreement to purchase land for a new ballpark in Las Vegas. So why can’t Oakland seem to keep its sports teams? Well, it turns out that there is a long tangled history to that question going back decades, but luckily two Bay Area sports insiders have just written a book laying it all out. That book is “Goodbye, Oakland: Winning, Wanderlust and a Sports Town’s Fight For Survival.” On this edition of KCBS In Depth we discuss the past, present and future of sports in Oakland with one of the book’s co-authors, Andy Dolich, a sports business consultant who worked in the A’s front office for over a decade and then went on to serve in executive roles for the Warriors and the 49ers.  Hosts: Keith Menconi, Holly Quan
