This Trail Blazers team isn’t one to make panicked trades. Yes they have the expiring deals, but there is a chance that other teams that are active in the trade market don’t want what this team has.
The contracts of Hassan Whiteside and Kent Bazemore are large ones. The trades that this site and others have proposed are probably pretty similar to what Neil Olshey and others are thinking, but the key problem is that teams may not want to take on Bazemore or Whiteside.
If the Blazers are taking on long-term money then that means the other team gets an expiring and then cap space in the 2020 market.
