Good team all around! I think second round exit, unless one of the goalies can play really well in the playoffs, and behind that defence, they may be able to.
Biggest weaknesses are goaltending and bottom 6 C (Smith is not a center, never has been). However, with the depth on this team, you could easily trade a/some player(s) to fill those holes. As it stands, this is likely a top 5 team in the NHL on paper, but I don't completely trust the goaltending in the playoffs. And if Drai or Horvat get hurt, you don't have any players that can jump into those roles.
