Starting out this season 3-5 and then 5-7, they subsequently peeled off a streak of 18 wins in 19 games in which LeBron James looked like the perfect puppet master. Then they dropped 10 of 14 and 13 of 19, looked terrible doing it, and gutted their team in the rare mid-season rebuild. Immediately after the trades, they rebounded to peel off two impressive-looking wins over two quality opponents (the Oklahoma City Thunder and Boston Celtics), looking 6 of their next 11, before peeling off 10 wins in the next 11 to somehow wind up with the fourth seed. Had it not been for a typically sloppy loss to the New York Knicks to close out, it might have been third. Last season, of course, was much the same. They started out 28-8, then lost 6 of 8, then won 10 of 12, then finished the regular season losing 15 of their last 26. We wondered allowed whether they could even change gear any more.   Turns out they could. The Cavaliers immediately peeled off two consecutive sweeps, winning 12 of their first 13 playoff games, in making their third straight NBA Finals. There is, of course, such a thing as playoff LeBron.
