He's certainly going to get a chance, simply because he is unlikely to play worse than last year. If he comes out and plays like he did in the playoffs (which wasn't great but still a big step up from the regular season) he will at the very least improve his trade value.
Crash used to be one of my favorite players, and I think the pace the Nets played at last year hurt him. An improved pace added to a pass first point guard in Rondo should help him put up better numbers assuming he isn't completely cooked.
That being said, if we can move him for an expiring contract we have to do so. The free agent class next year is going to be very good. Ideally we use this year to develop Olynyk, Bradley, Green and Sully, then after the year draft an impact player, and add an impact free agent, putting us right back into the playoff hunt with a young team that can grow into a contender.
