Hmm... come to think of it, that probably wasn't the best way to pose this question, since Finley at least considered any number of cities... Let's narrow it down: in which city had Finley actually signed a stadium lease before his request to relocate was turned down by the A.L.?
Apologies for asking too broad a question...
(Incidentally, I don't believe Seattle was ever mentioned while the team was still in K.C. - it was when the A's were already in Oakland that that plan came up...)
