Well, considering Porzingis is hurt a lot, I'm not sure, in a vacuum, how this makes Boston "better," per se. They obviously have eyes on Chris Paul, and since they tried to trade Brogdon first, their were aiming for a Paul/Smart tandem. But since the Clippers cried foul on Brogdon's physical condition (which has merit), they went with plan 1a.
IF Chris Paul is bought out and goes to Boston, the starting lineup looks formidable:
C - Porzingis
PF - Horfod
SF - Tatum
SG - Brown
PG - Paul
Bench:
Williams
Williams
White
Brogdon
(and I assume whoever they pick at #25 tonight)
That'd be the rotation. It's certainly more offensively gifted with Paul and Porzingis. But if you assume that Porzingis is going to miss 20 games, and Brogdon will as well, did Boston REALLY get better? We'll see.
Fire sale is ON in Washington. They got a solid PG in Tyus Jones. This works out well for him. This is the last year of his deal. He's one of the most underrated PGs in the league, and if he gets the chance to start all 82 games this year, he'll put himself in line for a big time FA deal next summer.
As for the Grizzlies, I'm unsure why they are doing this deal. Jones has the best assist to turnover ratio in the league, and when he starts, is a 15/9 player with good defensive. Sure, Smart is a better defender, and probably a touch better as a scorer than Jones. But I really think this is more of a wash for the Grizz, so I don't know what their motivation was for this.
