Why BRK do it:
They look to upgrade their squad as they don't control their picks over the next 4 drafts and they're a borderline playoff team
Dejounte's contract can be good if he upgrades his play as the lead guard on a team
Dejounte fit the Bridges timeline and they're desperate for better playmaking and perimiter defense
Why ATL do it:
They receive their sought 2 first round picks
Dinwiddie and Royce could be flipped to other teams for them to add a couple second round picks
