Let me ask you this? Does that Eakin play look like a typical hockey play? Do players normally crosscheck and charge through an opposing center off a draw and then stop skating? If you look at the full video, the puck goes back to Burns at the right point and Eakin is looking the wrong way / leaves burns alone with the puck (I know its not his guy but you dont leave BB alone with the puck at the point in game 7...).
This was a BS and dirty play absolutely worthy of a penalty, and since it caused injury, falls under the requirements for a major. I'll argue that forever. That said, the refs missed it and made a critical mistake in reversing their call or whatever incorrect protocols they invented to assess the major.
