Sorry, but you are wrong. This is the exact wording from

69.4 Contact Outside the Goal Crease - If an attacking player initiates any contact with a goalkeeper, other than incidental contact, while the goalkeeper is outside his goal crease, and a goal is scored, the goal will be disallowed.
A goalkeeper is not fair game just because he is outside the goal crease. The appropriate penalty should be assessed in every case where an attacking player makes unnecessary contact with the goalkeeper. However, incidental contact will be permitted when the goalkeeper is in the act of playing the puck outside his goal crease provided the attacking player has made a reasonable effort to avoid such unnecessary contact.
Lucic didn't make any effort to not hit Miller at all, hence it's illegal (and that's why he got 2 minutes). I don't think a suspension is in order though, but with Shanahan suspending guys for foul language and dirty looks these days, who knows.
Miller should have whined to the media about his own team though, who didn't do crap when it happened. Even if Kaleta had of taken a run at Thomas on the next shift, woudl have been ok with me. Miller can't hang around after the game to cry to the media and call out Lucic. THAT is a gutless move, Ryan.
