It'd be nice seeing Canada mix up the lines a little bit:
Marchand-Crosby-Bergeron
X-Toews-Giroux
Tavares-Thornton-Stamkos
X-Getzlaf-Perry
Fill in X with ROR, Duchene, and Couture - maybe Couture to Toews line because he shoots more and ROR to Getz-Perry as a Benn-lite or Duchene if they need more speed.
It keeps the top line together. It reunites Tavares-Stamkos who looked great together and adds a playmaker in Thornton. It give Toews a playmaker winger that should be more familiar with. It keeps the Getz-Perry dynamic.
I also thought that Stamkos looked good with Tavares (and vice versa). I"d like to see them on the same line too. I think Thornton would be very good between them, although Getzlaf would be fine too.
I'd like to keep Couture with Toews bc, so far, they've done well against other teams' top lines. Both are used to playing a shut down role. That's probably why the coaches don't want to move Stamkos from that line. ROR could be good there instead of Stamkos, freeing up Stamkos for a scoring role. I think ROR would be good but he was very sheltered in the only game he's played so far. (Understandably so since it was his first game and he hadn't had much time to get used to the team.)
I agree that it could be worthwhile to try Giroux with Toews since he's good defensively and having a playmaker on his right wing might be good for Toews. (Obviously not in the next game but at some point, at least in practice.)
Glad Crawford's scheduled to play. I thought he was outstanding.
