Excellent, better than many Sabre fans.
Definitely like how you paired LHD with RHD.
We will see how Granato wants to build the team but you are correct to keep at least two of the defensemen.
Comrie may be lost to the waiver wire as the Sabres can only carry 23 players, maybe he gets injured in the preseason LOL.

They can likely send any of the extra D or Comrie down without being claimed due to their cap hit. I think they will try to balance the minutes more so one of Dahlin, Power and Samuelsson is on the ice at all times and maybe double shift Dahlin with Samuelsson in the last minute of every period. But they would have likely made the playoffs last year with a few more games of Levi and if Samuelsson did not miss time.

For the goaltending I think they will run that trio again with Levi's minutes being managed. A slightly better defensive environment should help UPL and Comrie reach league average as they get used to the team's defensive structure (or lack thereof) and can better anticipate the chances that will be given up, even if they are high danger.
