I have not previously been an advocate for this, but given how putrid our offence has been, I would taken a run at Mikhael Granlund. He has put up a ton of offence over the last two years, and has 44 points in 51 games for SJS right now. I don't think he would be very expensive to acquire, although we would need to flip a mid round pick to a third party team to take 50% of his cap hit.
Our lines could look something like this:
Knies - Matthews - Domi | This is a rough facsimile of the terrific Bertuzzi - 34 - Domi combo of last year. Need to get Domi going and spread out the offence.
Patches - Tavares - Marner | Tavares has always been terrific with Marner, I think this would be a fantastic second line.
McMann - Granlund - Nylander | All offence line that you shelter. All fast, and McMann and Nylander are great together. Granlund only facilitates more offence.
Lorenz - Kampf - Jarnkrok | I think this would be a sneaky good fourth line: terrific defensively, and might actually score once in a while.
This is under the assumption that the Granlund acquisition is not too expensive, because I think we really need to add a piece of RHD as well. And someone better than Luke Schenn.
