Hasek's return raises questions in Buffalo

These are tough times for Buffalo Sabres GM Darcy Reiger, and not just because the weather in upstate New York is brutal this time of year. His world-class goalie, Dominik Hasek, has returned from the groin injury that had kept him out for half of the season, and just last week Hasek declared that he will postpone his retirement until after next season. Rookie goaltender Martin Biron has played well enough in Hasek's absence to keep the Sabres in the hunt for a playoff spot, and with Hasek now healthy, the Sabres are in a position to salvage what was once a throw-away season. So what possibly could be Reiger's dilemma?
