Plug Schartz into the right line and you're looking at elite line minutes. Defensively strong, tough, durable, and able to put up points with the best of them. Playoff warrior with Stanley Cup Pedigree who actually contributed heavily to the Cup win. Got the tools and his head in the right place. I've said it before and I'll say it again, if your team has forward needs, he can be that missing piece.
If the Blues move him it's for a necessity. The team needs BIG, strong, defensive-minded players who can slot in with the likes of Krug and Faulk so they can play their game better. The team can also use a sparkplug sort of player who can ignite a line of talent and convert the effort into points.
