Ya. The only way things move forward is to remove MB.
This would be my plan if I started as the GM today.
1) I am fine with keeping Galchenyuk and Drouin playing in their unnatural positions for the rest of this year to help ensure the good draft odds.
2) Draft Dahlin, Tkachuk or Zadina
3) Trade Pleks, Weber, Benn, Petry, Pacioretty at the upcoming deadline or in the offseason.
4) Have Galchenyuk and Drouin both play centre next year. The team will likely suck again.
5) Get another really good draft pick
6) In the next off-season, decide if you want Galchenyuk and Drouin on this team going forward.
7) Insert Dahlin, Tkachuk or Zadina into the lineup.
8) Start looking at free agents
9) Plan to compete in 2 or 3 seasons from now. Carey will still be young enough.
