Imagine a wing rotation of Devin Booker, Mikal Bridges, Jae Crowder, Cam Johnson and Bojan Bogdanovic. That would be one of the best wing rotations in the NBA with no team having more quality depth on from the wings. The move from Shamet to Bojan would increase their size as well along with the added scoring capabilities.
Why would Utah take this deal? No bad contracts, Landry "flippable asset" Shamet can be kept or moved and provide value in both scenarios while Dario Saric is a expiring. A likely late 1st is the most Utah should expect for Bojan's services as he's on a expiring contract, so they get a projected late 1st.
