This article and the linked article within present some amazing discoveries by Eric of BroadStreetHockey. Eric and the Broad Street Hockey crew (Geoff Detweiler) have been tracking each zone-entry during each Flyers game this year. They've come up with two fascinating results:
1. Entering the zone via carrying the puck in instead of by Dump results in basically TWICE as many shots on goal, even AFTER you take out odd-man rush and dump-and-change situations.
2. Neutral Zone play is far more important than previously believed and is far more of an area where player skill affects performance than offensive or defensive zone play, as opposed to simple randomness.
The first of these discoveries I suspect will be more interesting to the general LHHockey community though the 2nd is probably more of a landmark discovery, so I've linked in this fanshot the second dump-in vs carry-in article.
(If you guys aren't going to NHLNumbers regularly at this point, you're missing out. It's filling the hole created by BehindtheNetHockey becoming ArcticIceHockey and then some.)
