The only difference between Marleau on Rust and Letang on Mojo is that Marleau on Rust was much dirtier and the media is sweeping it under the rug instead of demanding action as they did against Letang.
Here's how it works. I kinda thought about it when Letang got suspended, or at least suspected, and it was confirmed for me.
When Letang threw that hit on Johansson, which was borderline in every way, every talking head was on a campaign to suspend him within ten minutes, be it on twitter or on TV. It was almost shocking how quick and decisive they were in calling for a suspension.
So I asked, and here's how the big media who are terrified of their NHL overlords operate. Their livelihood depends in a big way with the "insider" info they get from the head office, DoPS, etc. so they have to tread carefully.
We've all seen the e-mails, and we can assume the texts are even worse. When a bad hit happens, the e-mails/texts start to fly to DoPS with "Well, suspension or not?" DoPS usually knows pretty quickly whether or not there's going to be a suspension.
So when DoPS is dismissive of a hit and likely won't suspend they let the big boys in the media know. "Yeah, he might get a game" or "Nah, player should have protected himself better."
So when the media knows there's nothing coming, they sweep it under the rug in a "protect the shield" kind of way. The incident basically vanishes, and there's no outrage from the media, no "Man, I thought he'd get at least one game." They do everything in their power to defend NOT suspending, including changing the laws of physics. Some of the explanations for last night's hit are almost offensive in how insulting they are.
Of all the bad hits these playoffs, Letang's was nothing. Milliseconds late, millimeters high. I honestly thought he'd get a fine at most. But the TSN/SNet guys knew immediately he was going to get dinged. So the campaign began right away. "Oh, I think this is gonna get at least one game. Predatory hit to the head, late, what was Letang doing?!?!"
This is how these a-holes go about their business, carrying that pail of water for the League. It's disgusting.
