If I'm not making sense to you in trying to justify the suspension, that may be because I wasn't actually trying to justify one.
Outrage yes, statements like wanting the Red Wings to exact retribution for an incident involving other teams, wondering rhetorically why people like Savard get cheap-shotted, calling Lucic trash, I see plenty of outrage. Surprising you don't.
Your analogy though has nothing to do with what occurred.
Goalies are not fair game, the technicality of this wasn't really debated or inferred otherwise.
The charging nature of the penalty was the fact that this was obviously not incidental contact -- the refs had to call that. If it was not a penalty to finish the check on a goalie playing the puck far away from his crease as any other skater playing the puck would be vulnerable to this would have been a non-issue.
It's not anywhere close to an intent to injure call on the ice. It was not a double minor, it was not a major, there was no misconduct, no match penalty, nothing. It isn't just Shanahan that saw it that way. Lucic simply tried to play the puck and when he was too close he decided to just brace himself and deliver a hit.
There's no argument that it's a penalty (if we're arguing by the NHL's rules, my opinion obviously is another issue) but you're not making any sense trying to justify a suspension.
You can cherry pick a few posts and make it sound as if there's this resounding outrage, but you were the one saying Miller swung his stick like a girl after breaking a nail, so you hardly look impartial on the matter. Most of this thread to me is people just discussing it, with a few people who already hate Lucic chiming in. And maybe one who apparently doesn't like Miller.
Also, the Red Wing in question happens to be the brother of the player who got run by Lucic. I'm not advocating it, but it's not like it was someone randomly saying the Wings should attack Lucic. They were just speculating on if his brother Drew would do anything.
I chose that analogy because we're talking about a player who isn't eligible to be hit, much like a player without the puck. If you hit a guy without the puck the intent may not have been to injure, but because you're hitting a player who probably isn't prepared to get hit, the chances of injury are higher, intent or not.
