Portland gives the 11th pick to Houston.
Houston gives the 14th to Utah .
Utah gives future 1st to Portland (like 2014).
Portland does it for a proven PG. They get rid of Matthews and take a higher potential wing at 6 instead. They eat a year of Bell, but that isn't a big deal. They will get a 1st rounder from Utah in 2014, which will likely be in the 20's.
Houston gets a scoring center and upgrades from the 14th pick to the 11 pick. Jefferson could be packaged for Howard. They get some young player I know nothing about, but has a really high PER also.
Utah gets a lotto pick, draft Kendall Marshall. Also get Matthews to bolster 3pt shooting and defense. Gets Dalembert which helps defense.
