I know it’s BR, and some of these are a bit pie in the sky, but provided the economics work, I’d be up for just about any one of these trades if he really wants out:

I think Stef will be here next year, but I’d trade him yesterday for Brian Burns (or any of these first round pick ideas). No guarantee you’ll hit, but I’d invest heavy in WR in the draft under this scenario.
