I don't know what you mean by "jumped the penalty box."
Sgroi got cheapshotted and that's why he's skating around fuming (getting an unsportsmanlike in the process). Both he and Stroshein were in their respective boxes until Sgroi decided he wasn't done and crashed through the announcer's table to get to Stroshein.
Personally, I thought it was awesome and hilarious. Just like I thought it was awesome and hilarious when the Flyer fan fell into the box with Domi.
Wish he was still with the Pens...someone needed to do that to Kovalchuk.
“The most terrifying fact about the universe is not that it is hostile, but that it is indifferent. If we can come to terms with this indifference and accept the challenges of life within the boundaries of death, our existence as a species can have genuine meaning and fulfillment. However vast the darkness, we must supply our own light.” - Stanley Kubrick
What makes it so funny that all of you are getting all bent out of shape about it, is that Stroshein himself said something to the affect of "He was just doing his job", after the game. He was totally acting like it wasn't a big deal.
All Sgroi was talking about was how he had never been disrespected like that in professional hockey. (In regards to Stroshein cheapshotting him). The bottom line is that he lost his cool, and what he did was wrong, but ten games sounds about right to me. To say he should be banned for life is ridiculous.
