The NHL regular season ends tonight, and with it Souray's first year in Dallas also comes to a close, as Dallas missed the playoffs this year. Sheldon remains an Unrestricted Free Agent at this time, so I have my fingers crossed that he receives an offer soon, either an extension from the Stars or from another team. Free Agency officially begins July 1st, so it could be that nothing will happen until then. I think Sheldon enjoyed Dallas and did well there, so it wouldn't surprise me if they re-signed him - I'm actually more surprised that they haven't already done so.
Best of luck to Sheldon in getting a new/great contract this off-season and all the best next year!
