The Spurs could take on Andrew Wiggins' contract in a trade with the Warriors
Another option for the Spurs to move up in the draft would be to absorb a bad contract in exchange for a higher pick. The Minnesota Timberwolves in particular are projected to have a high lottery pick that has a 72.4% chance of conveying to Golden State.
With potentially two first-round picks, the Warriors will have financial incentive to package the Minnesota pick with Andrew Wiggins’ contract in a trade so as to not exceed the cap. While Wiggins had himself a decent season, factoring his contract, James Wiseman's contract, along with those of Steph Curry, Klay Thompson, and Draymond Green, the Warriors are one of the league’s most expensive teams.
Similar to last year's rumored trade involving LaMarcus Aldridge and the 11th pick for Wiggins and the number two overall pick, the Spurs could engage the Warriors about absorbing Wiggins' contract as an incentive to come to a deal.
So as to make the deal sweeter for the Spurs, the Warriors would include the Timberwolves' high draft pick in return for the Spurs taking on Wiggins' expensive contract. Such a deal would allow the Spurs to keep their own pick while adding another that could be as high as fourth overall.
While tempting, the Spurs would be saddled with Wiggins's contract, with 65.1 million owed over the next two seasons. Despite having plenty of cap space to accommodate such a contract, that price certainly still hurts. To justify paying him that much, they would have to value Wiggins as a player, particularly if he were to take minutes from some of the Spurs' current young players on the roster like Keldon Johnson or Devin Vassell.
