The realized value slightly favors Warriors. The Warriors acquired Jamal Crawford from New York Knicks for Al Harrington.
Golden State sent Al Harrington to New York on November 21, 2008 for Jamal Crawford. The Warriors wanted another creator after a poor start, and Crawford immediately took on a large scoring and ball-handling role. He played 54 games for Golden State and averaged nearly 20 points per game, giving the club the offensive usage it had targeted.
Harrington became a major scorer for the Knicks almost immediately and stayed through the end of the 2009-10 season. His contract timeline also fit New York’s effort to create flexibility for the 2010 offseason more cleanly than Crawford’s longer deal. The Knicks therefore received both real on-court production and a roster-planning benefit.
Golden State did not keep Crawford long. In June 2009, the Warriors traded him to Atlanta for Acie Law and Speedy Claxton. Neither incoming player became a major Golden State contributor, so that branch was modest, but it still shows Crawford remained a movable asset after his productive 54-game stay. His Warriors value was concentrated rather than durable.
The Knicks received more direct games from Harrington and improved their 2010 contract positioning. The Warriors received the more dynamic scorer for one season and then converted him into another package. Neither side created a franchise-changing asset, so the completed result belongs in the narrow-margin range rather than being framed as a steal.
Harrington and Crawford weren't simply interchangeable scorers. Crawford gave Golden State substantial offense during a 54-game stint, but the club moved him again in June 2009 rather than building around that production. His next destination was Atlanta, with Acie Law and Speedy Claxton coming back to the Warriors. Harrington remained with New York through 2009-10, giving the Knicks far more time with the player they originally acquired. His shorter contract also aligned with the club's much-discussed 2010 summer roster reset. That strategic advantage wasn't a later title or a guaranteed free-agent signing, and it shouldn't be valued as one. It was a measurable difference in flexibility. The trade was close enough that Golden State's slight grade advantage depends on Crawford's player value during his short stint rather than on years of sustained Warriors production.
Slight Warriors Edge — Golden State B, New York B-. Crawford gave Golden State immediate scoring and still carried trade value the following summer. Harrington gave the Knicks more games and fit their 2010 cap plan, so New York’s return was plainly useful. The small grade gap reflects two reasonable outcomes, with Golden State getting the slightly stronger player-value peak.
