Cheap shot a player? There was no cheap shot there. As a firm believer in objectivity over fan favouritism, I actually think that was NOT a penalty...
Van Ryn turned in an attempted 180 when he saw TK had him lined up and that is why TK hit him from behind... but, the Rule states that such a situation is NOT a penalty:
Rule 44 – Checking from Behind
44.1 Checking from Behind – A check from behind is a check delivered on a player who is not aware of the impending hit, therefore unable to protect or defend himself, and contact is made on the back part of the body. When a player intentionally turns his body to create contact with his back, no penalty shall be assessed.
Though I guess it could be called a penalty if the referee interprets that last sentence to mean the player turns specifically or deliberately to create contact with his back and not just as part of the play...
I'm not denying TK hit Van Ryn in the back, because he clearly did... but the reason TK did it is why it should NOT have been a penalty and why I don't blame TK at all for the incident...
If you watch it in slow-motion you can see how the play developed... Van Ryn went into the corner at an angle as he should have, TK saw that and had him lined up for a big hit, Van Ryn saw TK in the glass and attempted to reverse direction and not only stopped, but started to turn his back to TK (look at Van Ryn's left skate during the play, he stopped and was about to push off in the opposite direction), which is probably the worse thing he could have done... if Van Ryn had continued in the same direction, or even just stopped without turning, TK would have hit him with a very hard, but perfectly clean, check...
Now consider that all this happened at full speed, how is TK supposed to stop when Van Ryn literally turned at the last instant before contact?... Watch the YouTube clip and try to freeze it as TK's skates are on the goal line... see how close he is to Van Ryn, probably within 3 feet, yet Van Ryn still does NOT have his back to TK even at this point... TK is probably only a foot away by the time Van Ryn has turned...
this is the text-book definition of the checkee 'causing' the hit-in-the-back and exactly why that sentence is in the Rule Book... it was a clean play by TK which Van Ryn turned into a dangerous/illegal play by his own actions...
On this picture, you clearly see that Van Ryn his heading towards the back of the net (look at his skates), or in a position to stop. At the same time, look at Kostopoulos who's already in motion to hit him, passed the goal line, leaning forward to hit him. Not in the back, but on the side!

Look at the picture again, look how close Kostopoulos is from Van Ryn, within the red goal line, how his body is starting to move forward to hit and yet, Van Ryn is sideways to TK at that time. This shows without any doubt that Van Ryn turned at the very last second and TK couldn't stop.
It's an unfortunate incident that I'm sure TK feels bad about, but Van Ryn brought it to himself by putting himself in a vulnerable position in order to avoid the inevitable check. Furthermore, he bend down forward in doing so, a big no-no.
