There are a few teams that come to mind when talking about being a disappointment.
Sixers will probably be another 2nd round exit with or without harden so is it really a disappointment anymore? this is who they are
Clippers will also most likely be an early playoff exit when Kawhi and/or PG gets eventually get hurt. Or westbrook boneheaded plays costs them games late in the 4th.
I dont know what people are expecting from dallas. Got a superstar in Luka but Kyrie has got to be the most destructive player in NBA history. He will somehow implode this team. Cant figure out exactly how yet.
I think the Suns will be the biggest disappointment this year. They are one of the title favorites. However this glass cannon build wont fare well in the playoffs. I can see a big physical team like the Lakers dominate in the paint and knock them out. Sure the big 3 can put up 90 but it wont be enough.
the heat always find a way to embarrass that team
