The St. Louis Blues have signed C Patrik Berglund to a 3-year deal ending speculation that he would be sent off to Ottawa in any type of Jason Spezza trade. Perhaps there are other players that could be substituted in any attempt to acquire the star Senator.  Perhaps we will find out by tonight's NHL  Entry Draft.The Chicago Blackhawks have signed some key support personnel by inking backup G Antti Raanta and F Ben Smith to 2-year deals. The Hawks are tying up all their loose ends as they head into the Draft tonight.  Speculation is that they are heavy into trying to acquire the 1st overall pick from Florida. Tonight should be very interesting as there are a ton of rumors going around the league today.
