1. Boston Celtics

Adding Gordon Hayward and Kyrie Irving puts them in the same class with Cleveland.

2. Toronto Raptors

It’s business as usual for the lone Canadian franchise.

3. Philadelphia 76ers

Time to see all their top tier talent make a playoff appearance.

4. New York Knicks

The era of Kristaps Porzingis has begun.

5. Brooklyn Nets

It’s a better roster, but it will be another transition year in Brooklyn.
