Quoting: CapFriendlysFinest
I agree how this it will likely be, it just scares me so much. That last pair is concerning. Honestly, the deal is for if Reilly is missing a decent amount of time, but not alot of time. Mike Reilly adds alot of good for not alot of cap. The only down side is the extra year he brings with him, but again, if Muzzin career is done, then I don't hate it.
They already have a surplus of LD though even if Muzzin is done, also they won't know until February.
I could see them trade for Timmins if they don't like Mete's play, then run:
Gio-Liljegren
Benn-Holl
Sandin-Timmins
If they are still bad, then I think it would be better for them to look at Soucy, Gavrikov, or Jensen. If they need a big minutes eater then Klingberg. These guys are going to cost more than Rielly but smaller chance that it leads to future complications that could be costly.
Brodie had a set back but I think he's still week to week, so it really depends if they can stay afloat or not in the standings while they are out.
