I am starting not to trust Matthews injuries meaning: He seems to be injured quite often.
What I am going to suggest may be one of the most off the wall, crazy, but a balsy move for the now. ( which would definately shorten "our window") yet stregthen our center depth and imo be a better well rounded team.
Also would have to consider that other moves could be made down the road to tweek us even further.
My propsal is:
Matthews
Minten
Robertson
traded to Pittsburgh for:
Crosby and Malkin.
Points would not be lost because Crosby and Malkin should be able to cover the loss of Matthews totals.
Crosby could lead the team like a true Captain centering the first line.
Knies - Crosby - Marner
Domi - Tavares - Nylander
McMann - Malkin - Lorenz
Dewar - Kampf - Reeves
