Smith isn't really a big guy, nor does he really use what size he has all that effectively, and he leaves a lot to be desired in other aspects of his game. He wins faceoffs, and thanks to a completely unsustainable Sh% has hit a career high in goals, but don't be fooled, he isn't going to provide offense long term, and his defensive play is average at best.
Between Paul and Lazar, and Pageau, there isn't a lot of room for him as a center in the bottom 6. When MacArthur returns, there's no way we need Smith in the top 6. Hoffman and by the looks of it Dzingel make LW in the top 9 out of the question for him. Now's the time to take advantage of Smith's all time high value. You should be happy, it might make room for Paul in the lineup.
