Miami doesn’t really have anything to give up. Sorry, Caleb Martin and Gabe Vincent isn’t going to get it done. Neither is Herro. Obviously they can’t give up Butler or Bam, so I don’t see how that scenario would shake out.
On the other hand, Brooklyn has a lot of pieces and Bridges might be a guy that’s good enough for them to say yes to, while leaving Brooklyn with a solid core. They’d presumably be putting their eggs in Ben Simmons’ basket, but with guys like Cam Johnson, DFS, Claxton, Dinwiddie… makes sense to pull the trigger and take a shot. Bridges, Harris (for salary), and multiple picks for Lillard.
