I was at the game, so didn't really see hear any explanation about why it wasn't a penalty for targeting? The student section was pretty animated for the rest of the game as a result and I tend to think with some justification too.
It was clearly helmet to helmet...did the broadcast explain why it wasn't flagged?
Basically it came down to three factors:
1) Pierce lowered his head
2) There was no apparent intent to injure, defender didn’t launch up or into Pierce’s head
3) Pierce was not a defenseless player
This was Gary’s and the replay ref that they call up from New York or whoever he sits explanation as to why it wasn’t targeting. I’d be fine with this, except I’ve seen players flagged AND ejected for much less, which is why the rule is fuking stupid.
