I think odds favor Hasek just based on the team in front of him however will he play enough to make a contribution for you is a real hard question - I think they are trying to preserve him the best they can for the playoffs.
Ellis seems to have found his game as have the Preds - he might be the better goalie of the moment - however, I would look at the matchups closely and try and find out what you can about Hasek\'s status and go from there.
