Jefferson has a contract that is similar to that of Jackson's, but Jefferson is signed through 2013-2014 season, when he will have a player option. So, in essence, the Warriors have agreed to spend $11 million extra to get Jefferson.
Why T.J. Ford is involved in this deal is quite puzzling. On Monday, he announced his retirement after enduring several career-altering injuries.
However, perhaps the most intriguing aspect of this deal is the first round draft pick. Yes, it is lottery protected (if the Spurs get the No. 1-14 picks in this year's draft, they get to retain the pick), but that should not be an issue, as the Spurs are second in the Western Conference.
This pick should end up being in the mid-20s. The Warriors' own pick in this year's draft is currently owned by the Utah Jazz. However, it is top-7 protected (the Warriors keep their pick if it is number seven or lower).
