Assuming we're stuck with Smith 4C is probably the ideal spot for him, honestly. I'd much rather see him jettisoned to give that role to a younger/cheaper option, but given the unlikeliness of that happening I hope (DJ) Smith marks down (Zack) Smith in sharpie for the 4C role. Speaking of overpaid veterans who are terrible, Boedkker needs to be stapled to that 4th line too. Holy cow is that guy ever a medicore player. He's not good offensively, he's not good defensively, he's not physical, he's just kind of there.
Let the kids play in the top-9 with our decent veterans (Pageau, Tierney, Ryan) sprinkled in and ride out Smith and Boedkker's deals with them on the 4th line getting ~10 minutes/game.
