If you want to look at the Silver lining, they pushed the team that was in back to back finals, current champs to game 7.
Seth Jones and Marchand basically killed the Leafs yesteday, Jones with great positional plays, closing the gap, helping the forecheck and lead their way to the victory. And the rat is someone that I would sign up just to stop him from eliminate the Leafs every year.
Shanahan is probably gone, so we can expect some changes.
This core must change, but why would the lose Marner for free ? They should find comon ground and not give him full NMC. Marner's value is high in the league and Leafs could bring out some great pieces in return.
Tavares will probably be gone, Marner is probable going for free (and will hurt the team even more) , Knies needs to be resigned.
The toughest part is knowing that this team needed a Ryan O'Reilly type of player that they had it and weren't able to resign. They need an equivalent of Gary Roberts to take them to the next level.
Colorado is also without a game 7 win in the recent years (7 straight losses in game 7, the difference is their Cup) and perhaps both Teams can benefit from a Star trade (sign and trade Marner)
Anyway, this will be an interesting off season.
