Trade for Portland's #3 pick, get either Brandon Miller, Scoot, or Amen. Take Knox as collateral and you have yourselves a contender.

Knox has improved his shooting with the Blazers, he's just not given enough playing time. Any top 3 first-rounders are good enough to be starting, plus you get to save cap space by trading away Wood and Bullock. Use that space to sign a good role player.
