As it stands right now, the Orlando Magic are the last team in the entire NBA standing undefeated. Not many people would have predicted that, but there you have it. Other teams like the Hawks, Pacers, 76ers and Nets have all looked very strong as well. Even the Cavs are 3-1.
Looking at the bad now, the Raptors have started the year with a not so good 0-3 record. The Milwaukee Bucks, last year's #1 seed has also gotten off to a losing start with a 2-3 record. Although things look good for some of those decent teams, I still believe that the Raptors and Bucks will turn it around before the season finishes. There is still plenty of time, but who knows what's going to happen.
If I had to pick a winner at this moment to represent the Eastern Conference in the NBA Finals, it would probably have to be the Brooklyn Nets. At 3-2, Brooklyn has looked very strong when KD and Kyrie are draining their shots. With guys like Joe Harris, Deandre Jordan and Spencer Dinwiddie surrounding them, it's going to be hard to slow them down come playoff time.
