Go to Penn State's website and check their photos vs. Stonybrook (Indoors) You'll see pockets a full inch too deep, the sticks are dry and the pocket materials' are not that elastic they are much more firm than you give them credit for. Do you know how a draw string is strung? If you did you wouold be able to spot them in most any photo. A shoelace is used to tie the bottom of the mesh to the 4 holes in the head closest to the ball stopper. The use of the Shoelace is so that when it is pulled to make the pocket legal it is thick enough to not easily slip back to illegal depth when ref's drop the ball into the pocket. This string is also identifiable by the extra knot tying the ends together giving player a loop for their finger to fit into for easy and quick pulls.
When I get old and lose my mind I will forget more about this sport than you will ever know about this sport.
Is there a rule about cross-checking in the rule book??(YES!) Why aren't they called?
Is there a rule in the book about the legal depth of pockets?? (YES!) Why do so few get caucht??
The Rules are there and I don't blame the players for cheating---because if you ain't cheatin' you ain't tryin' hard enough.

The Problem is how poor a job ref's do of controlling games and keeping them within the rules.
If a ref sees a slash he should call it! Right?
If a ref sees a stick he thinks might be too deep he should check it! Right?
The rules are only a joke because ref's don't make the calls!!!!!
