Here's some inside information.
1. Which East team should be most excited about its upside?
Amin Elhassan, ESPN Insider: Boston. Right now the Celtics are in the gravy portion of their life cycle: not good enough to warrant expectations but good enough to beat anyone in the East. The home stretch and playoff run awaiting Boston will give valuable experience to its young roster, experience that will carry over to future permutations of the Celtics and/or increase trade market value this summer.
Tom Haberstroh, ESPN Insider: Boston Celtics. They have a great coach, a winning franchise, a top-notch culture, young talent and assets galore. Even though the Cleveland Cavaliers have the highest ceiling, that also comes with enormous expectations. The Celtics can play out the season feeling giddy about their future whereas the Cavs might feel burdened by it.
Bradford Doolittle, ESPN Insider:Boston in a runaway. For the remainder of this season, if the Celtics play to their point differential, they'll win a playoff series and pose a major challenge for whoever they play in the second round. They'll enter the offseason perceived to be "one step away". By then, they might own the top pick of the draft if the lottery goes well. Then free agency hits, where Danny Ainge has the cap flexibility and pieces to acquire an upper-tier star.
Kevin Pelton, ESPN Insider: The Boston Celtics. On May 17, the NBA will hold its draft lottery before Game 1 of the conference finals. It's conceivable the Celtics could win the lottery (via the Brooklyn Nets) and then take the court in the Eastern Conference finals. And if that dream scenario unfolds, Boston would become a very interesting player in free agency this summer.
David Thorpe, ESPN Insider: Gotta be the Pistons. Think about it. Andre Drummond is still just 22, Stanley Johnson is a teenager, and both have significant upsides to uncover. But that's just the beginning. Tobias Harris and Kentavious Caldwell-Pope are 23 and each has a solid future ahead, while Reggie Jackson has made the big jump to playing like an All-Star. Combine these "kids" with a coach who knows how to build cohesion around a team identity of defense and playing the right way and you have an attractive team to veteran free agents.
