So how do we dump our entire 3rd line?
I don't think the entire line necessarily has to be dumped.
The Kadri/Saad combo doesn't seem to work so well, but Nichuskin-Kadri-Burakovsky does, so keep that line intact and move Saad to the 3rd line to start with.
Compher needs to be the one receiving the puck at speed while skating up the right wing, and not the guy at center ice responsible for running the transition through the middle. Compher isn't a bad player, he's just being asked to play a role that is the anti-thesis of his actual strengths.
We clearly need a 3C for that line to work. Compher isn't the answer. Jost isn't the answer. Namestnikov wasn't the answer. Bellemare isn't the answer.
Newhook
might be the solution this season for the playoffs, but that depends on how ready Sakic thinks he is, and also on his willingness to burn an ELC year. I'd be wary of putting all our eggs in the Newhook basket though as far as 3C is concerned, because if it turns out that he's not ready then we're stuck with Compher at 3C for the playoffs which isn't ideal.
I would much rather see Sakic acquire a 3C before the deadline regardless of whether or not Newhook is ready, and then just move that guy to 4C if Newhook pulls a Makar, as that would safeguard against the possibility that Newhook isn't ready to be a 3C right off the bat this year. I do think that a line of Saad-Newhook-Compher could be quite effective though, as there's a good combination of speed, skill, and net-front presence between that trio, and all 3 of them would be playing in their best positions.
Whatever the case, one way or another Sakic really needs to find a way to acquire a two-way center who can transition the puck and distribute the puck to the wingers better than Compher does. Until he does, that line is going to be an inconsistent and anonymous mess on the ice because they simply won't be effective at moving the puck.
