I pass the puck between my players to get that goalie moving and cycle the puck until the opposition is dizzy and on average I'd usually see an average about 1.7 CPU infractions per ten minute period game and it's usually slashing or tripping only when the puck receptor makes a quick turn and the CPU is late with a stick lift or poke check.
I hope it's been addressed in 16's latest tuner. I'd settle for more calls of anything tbh but it's been years since you could rely on the CPU to get checking from behind / boarding etc. The actually variety is very poor. All regular occurrences in NHL 11 when the sliders worked - no matter your playing style.
