I think King should be the odd man odd. He doesn't do much out there.
I was thinking that earlier in the season, but King is too valuable in the playoffs. Plus he's playing great on a line with Stoll and Lewis. I also love having a 4th line of Clifford/Fraser/Nolan.
Penner is kind of the odd man out. It's going to be a tough decision to sit Toffoli when he's clearly able to make an impact on the game. I think actually having Toffoli on a line with Penner would be interesting. When Penner is throwing his body around and making great passes (which he is very capable of), Toffoli can bury them.
I don't think having Carter and Toffoli on the same line make sense. They are both snipers. You need a physical guy, playmaker and a scorer on a line. This is the recipe for success. You can interchange certain aspects of it, but you definitely need to spread out your snipers. We thought that Gagne was going to be that guy, but Toffoli is clearly able to fill that role.
I think if we can get Greene and/or Mitchell back by playoffs and Quick gets sharp, it's going to be very difficult to play this team.
