Within the last 50 years, which of the following were the best team relocations in sports history?

The Best is probably the KC A's out of oakland since they had good team when they were Phillie A's but sucked in KC, and then became a good team again in Oakland also St Louis Browns to Baltimore, i never even knew they started out in St Louis, they must of been bad before they became the O's, and you cant really count the Jets and Giants heading to Jersey, its still the same market. Otherwise, most of them arent that good, i mean the Giants and Dodgers leaving was bad, the NFL leaving LA was bad (even though LA dont give a **** about football) and the Colts and Browns leaving baltimore and cleveland, those were all bad ones
