tripping not penalized

@jmach 

You only get called for tripping if you trip the carrier with your stick. If you're seeing this happen and it's not being called, please get a video of it. Knocking players down with incidental contact that aren't carrying the puck won't get called for tripping.

Well then clipping/roughing/interference penalty whatever situation is, the point was more that there are so many penalty not called for players throw their body into other players taking them away from position or stopping their forward progress illegally so many times its not called for penalty.

this is still bugging, not allowed in icehockey to take away a player with the body like this
