Very sloppy programming. If a player skates over an opposing player's stick, it's not a tripping call. If a player initiates a stick lift from close in, it's not a high sticking call. If a player is up against the boards and the opposing player reaches in to knock the puck loose and makes contact with the puck but the opposing player falls because of the opposing stick, it's not a tripping call. Very sloppy programming and it smacks of not understanding the fundamentals of the game. Hopefully they'll fix it in 20.
