I like Crowder's defense at the 3 position. With Smart-Bradley-Crowder we have a very tough perimeter defensive crew that we can put out in close games.
Now we just need to get/draft an elite paint protecter, and this team could have a top 10 defensive unit next season.
I don't feel like Crowder will cost much money to keep. He's making less than 1m in salary this season.
