I still like Smith as a 3rd or 4th liner just not with Neil and Greening. It's a terrible line and needs to stop.
Greening-Pageau-Condra seemed to have some chemistry last year, why not try that again?
Without calling up Zibby I'd try this :
Michalek - Spezza - Conacher
MacArthur - Turris - Ryan
Greening - Pageau - Condra
Smith - Da Costa - Neil
Smith takes the draws and then plays wing.
I would also like to see what it would look like flipping Smith and Greening. Balances the lines a little more in terms of talent and toughness. Smith still takes the draws.
I like Hemsky, but I don't see where he'd fit on this team.
Michalek-Spezza-Hemsky
or
MacArthur (Greening?)-Turris-Hemsky
or
Greening/Conacher - Zibanejad - Hemsky
He'd be injured within 15 games anyways.
