Any trade involving Jason Spezza may have to wait until a few other dominoes fall in the NHL center market. Brad Richards is now a free agent after his contract was bought out by the Rangers and the Canucks' Ryan Kesler and the Sharks' Joe Thornton also appear to be on the trade market. If Paul Stastny is not signed by the Avalanche in the next nine days, he will become an unrestricted free agent. So there are plenty of options for teams looking to add a top line pivot.
