It’s a classic case of buyer’s remorse. The Philadelphia 76ers have waited and waited on Andrew Bynum, who has more outrageous hairstyles than minutes played. He broke the news Friday that his surgically repaired right knee swelled after his last workout.

So Bynum may never appear in a Philadelphia uniform if he decides to have more surgery, meaning the down-on-their-luck 76ers got a half-season of Jason Richardson for their participation in the Dwight Howard deal, getting fleeced because they gave up first-round pick Maurice Harkless and double-double machine Nicola Vucevic, who is tied for fourth in the NBA in rebounding.
