SD, I'm strongly disagreeing with you. And I am (or was, at the start of the season) a big, big Ovechkin fan.
First of all, the suspension may be automatic, since this is his *third* game misconduct. Although I did read that it may not be automatic because it's a different infraction from the last time (boarding vs. kneeing), and the length of time since the previous one (although the Olympic break did extend that somewhat artificially).
Second, that was *not* a hockey hit. This was very similar to the foot races that Cherry likes to show to convince people that we need to get rid of touch icing. When he reversed the puck he was turned around in a very awkward position. While in that position he actually had his back to Ovechkin, so that was a hit from behind. It really wasn't a hit but a shove. If he had just hit him, then Campbell would have been up against the boards at the time of impact, and probably ready to brace himself. As it happened, Ovechkin extended his arms to shove him into the boards, at the very moment when Campbell was completely vulnerable: he was off-balance after reversing the puck, his arms/hands were not in front of him to brace for impact, he was 3-4 feet away from the boards so even if he had his arms out in front of him he could not brace for impact.
I hate to say it, but it *almost* looked like Ovechkin rushed the hit (by extending his arms) because he knew the damage would be much less if he simply continued skating and tried to hit him.
