Since memory is mercurial, here's an article from Zach Lowe assessing the deal.
DeRozan as a centerpiece is a disappointing return, but also one that reflects market realities. Gregg Popovich does not want to finish his career in a rebuild. The Spurs never showed interest in packages -- including Boston's -- heavy on picks and unproven players, sources have said. The Celtics would not swap any of their core guys, including Jaylen Brown, perhaps the most interesting Leonard trade chip in the league, without some assurances about Leonard's health and future plans, sources have said.
Philadelphia's potential package of Robert Covington, Dario Saric, and the Heat's unprotected 2021 pick didn't move the needle. It's unclear if the Spurs had interest in Markelle Fultz; the two sides never discussed him seriously, and the Sixers would not have parted with him, sources say. The Spurs made it clear any deal with Philly would require Ben Simmons or Joel Embiid (likely Simmons), and the Sixers weren't going anywhere near that, league sources say.
Talks with Boston and Philly stalled weeks ago. There was no frenzied last call Monday or Tuesday. San Antonio over the past four days lowered its asking price with a few other potential Leonard teams, according to sources around the league, but it was hard to build any realistic deal.
DeRozan was decent in Games 1 and 2 of their second-round series before vanishing in Cleveland. He finished the series 0-of-9 from deep. He spent the fourth quarter of Game 3, his last meaningful game playing for a team and city he grew to love and that loved him back, on the bench as the Raptors rallied (but still lost) without him.
Poeltl is solid -- a nimble center who thinks and feels the game at a high level. Losing him makes the prospect of someday trading Jonas Valanciunas -- a Nurse favorite, by the way -- more fraught. But he also might top out as a nice backup, or fifth starter who struggles defending lineups with five 3-point shooters. The first-round pick is about as low-value as one can get.
It's possible Boston, Philly, and other teams loaded with picks weren't offering their best ones -- including the juicy 2019 Kings pick the Sixers and Celtics have divided like a summer timeshare. But a franchise with different priorities could have bid those sorts of teams against each other, and come out with an interesting collection of future assets.
The Spurs lost some leverage when LeBron James opted out of his deal with Cleveland, and lost more when he joined the Lakers without issuing any immediate mandates about superstar partners. They were going to lose a little more every day until training camp.
They didn't start with much, either. Nobody knows if Leonard is healthy enough to regain status as a top-five player and MVP candidate. (He still has to pass a physical.) Suitors feared his impending free agency, and his reported preference for one of the L.A. teams.
