Always believed that players who are playing well will carry that over to the SO. Obviously this is within reason - I don't care how well Aaron Voros is playing in a particular game, he's not in my top 3. But is Callahan flying? He's in. Did Anisimov look like he was really into the game (like last SO)? He shoots.
This is especially true given that our "specialist" Kotalik is out of the lineup.
