Brandon Jennings is a bold young'n. The Bucks point guard said that Milwaukee would upset the heavily-favored Miami Heat in six games. There's nothing wrong with believing that you're going to win every game, but the mistake he made was when he tried to get his Ali on. Predicting the exact time the series will end no doubt gave Miami some motivation. However, if Brandon's wish comes true, their upset will be at the top of this list. We don't believe we'll see a huge upset in the early round of this year's playoffs, but it doesn't hurt to look back. So, from the 76ers last year to the Nuggets in 1994, check out the Biggest First-Round Upsets in NBA History.
