There's something fishy about the entire Dennis Wideman situation. It was an odd incident to begin with - there's a reason we never hear about, let alone discuss, players crosschecking linesmen - but now, there's a whole new factor to take into account.
Prior to Wideman crosschecking Don Henderson, he himself was hit, and grabbed his own head before making his way back to his bench. It was seconds after his own head was hit into the glass he encountered Henderson, and subsequently hit him.
The NHLPA's statement of appeal for Wideman's 20-game suspension cites "medical issues" presented at the nearly-two hour hearing he had on Feb.
