I think Yzerman needs to sign Bertuzzi at this point in the rebuild. That doesn't make him untradeable in the future, not in the least. See how Yzerman dealt Mantha a year ago, and overall, we're probably pretty pleased with the return on that deal so far. There is room under the cap now, sign an impact FA or two, keep drafting well, make some trades here and there when the pieces fit your purpose, and see what the next HC and his staff can do to get the team closer to the playoffs. If he stays healthy, and the Canadian restrictions on his travel go away soon, he will have trade value for the next few seasons, at the very least. No need to trade him now. JMHO.
