This thread is going nowhere. Those of us who liked the trade said that the advanced stats, specifically those that favor some sort of on-off measurement, liked Derrick White a lot, despite his mediocre counting and shooting stats. Those stats have continued to like White as a Celtic, and the Celtics play well when he’s on the court. They also showed that the Celtics did not play all that well with Richardson.
Those of us who didn’t like the trade pointed to his bad shooting stats. Those have continued, as did Richardson’s shooting in San Antonio. The one thing that has changed is that the Spurs play very well with Richardson on the court.
Accordingly, it’s possible this trade was better for the Spurs, because they got someone who offered similar production in addition to a draft pick. At the same time, the Celtics got a player who helps them more than the players they gave up (anyone still gnashing their teeth about Langford, who played two games for the Spurs and was then hurt again is just being absurd), is under contract longer, and actually saved them money next year (White + minimum is less than Richardson + Langford), which is really important for a team at or above the tax line.
So perhaps this was, heaven forbid, a win-win trade?
