Phoenix is probably the best team to help with eating our cap. Sarver is known to be a cheap owner. I'd take on Childress or Warrick for a first rounder.
I wouldn't. The Raptors are better off just being players in free agency than doing that. The key to my idea is to not take on long term burdens. When Childress and Warrick expire doesn't appeal to the Raptors nor do they offer long term hope of being part of the long term solution.
