C'mon lol.
You dont think coaches have gameplans that players are expected to follow. And you don't think that if the players don't follow it they ride pine or get chewed out? You even said it in your post "thing is teams get video on every other team". So what do you think they do with that information? Nothing? Or come up with a gameplan.
To support my theory over yours I present you Nate Schmidt. Great player for the caps. Great player for the knights. $&!#ty with us. Great for Winnipeg.
That's suspicious. I guess that was all on him eh. Must not have liked the food in Vancouver.
Or maybe it's the coaching staff and the way they deploy players.
