They are old, and their window has all but closed. They can sign another aging vet or two, and hope for the best, and risk falling flat on their face, or start a slow rebuild. They would still want to stay respectable around Duncan, however, as it would be a shame to send him into retirement on a lottery team.
Miller, Joel, Webster, Rudy, and some combo of Claver, Kopo, Freeland, picks for Parker and a sign & traded Manu. Or include Bayless in there, mix and match the pieces of Rudy, Webster, Bayless euros and picks, combined with Miller and Joel's salaries. Miller, Rudy and Martell, along with Duncan, hill, Blair, Jefferson and McDyess, as well as Splitter coming over and possibly Freeland, Koppo, and picks could keep them competitive, while also giving them young pieces for the future. Super long shot, I'm sure they'll just try to re-tool around Parker, but worth calling about.

and I'm sure someone would offer more.
