The NBA playoffs begin on Saturday and it could prove to be one of the most interesting postseasons in recent memory. Defending champions the Golden State Warriors swept all before them in the Western Conference last season, before dropping just one game as they regained the title from the Cleveland Cavaliers in the Finals. It is hard to see them having it all their own way in the West again this time around, while the Cavs are by no means certs themselves having endured a campaign of turmoil as the Philadelphia 76ers made huge strides.
