Why no confidence in Matt Greene?
To be honest Bergeron, Smid, and Hejda all worry me more, especially on the defensive end. I haven't seen anyone play, but from your (and others) accounts, Smid seems like he's playing quite well, so hopefully he plays well enough to make the team.
But I thought Matt Greene played better and better down the playoff stretch, even if he was good for a penalty a game. I have a good feeling about Greene.
