Blazers have Ja, Dame, Jrue, and Scoot at PG. Scoot is entering the final year of his rookie contract and it would be unlikely to sign him long-term when they have Ja, Dame, and Jrue all under contract next year for a combined 96.2M. They also have no depth at PF and get Vanderbilt while have Knecht with 2 years on his rookie deal.
Hawks get a year to see if Scoot is a long term piece.
Lakers get Kuminga and free up 2 roster spots.
