Bagley is wanting out of the Kings. In this article they talk about Langford and Grant Williams and a second. Instead I put Williams, Parker and Edwards. I would give them the 2nd rounder they suggested but didn't involve it in this trade. Langford if I'm the Celtics I'd be trying to keep and he's also hasn't seen the court much so might be easier to keep. Williams and Parker make up for the size of Bagley and Edwards gives them some shooting. The second rounder is needed I believe to sweeten the deal, honestly if they wanted a 1st I'd be willing to give if Bagley was willing to sign an extension.
The way I did this was Wall coming to the Celtics but it would be after a buy out. No way I could figure out how this would work but I believe this would work. Celtics have still some TPE money so Wall could be used for this. I believe Wall with change and not needing to be the star would help the Celtics. If he's bought out either a one year prove it deal for 10-12 million or try a 20-25 million over 2 years. This give you another veteran which is needed in the starting five. Williams, Tatum, Brown, Smart and Wall is a nice looking starting five. Then having Kanter, Horford, Nesmith, Richardson and Schroder being a second unit.
