The heat does this to get more competitive and they get a true superstar in Lillard. I didn't put picks in this trade but I don't think the Heat would be giving up any picks. Because they gave Herro to the Knicks the nicks would send their picks to Portland. The Heat's lineup would be : PG : D.Lillard SG : C.Martin SF : J.Butler PF : D.McDermott C : M.Robinson
The Knicks's lineup would be: PG : J.Brunson SG : T.Herro SF : J.Grant PF : J.Randle C : J.Nurkić (It doesn't make much sense on why the Knicks are part of this trade but i like the idea of Herro playing for the Knicks. Knicks fans would go crazy in the street for every 30+ points games from Herro.)
The Blazers' lineup would be: PG : S.Henderson (if he is available. If he isn't they sould take Amen Thompson, I think Brandon Miller is gonna be a bust.) SG : RJ.Barrett SF : S.Sharpe PF : C.Reddish C : B.Adebayo 6thm : A.Simons
The Spurs get an experianced PG to pair with Wemby and they will have so much cap space next year.
