I never want to hear the words Game Management again, for as long as I live. For those not familiar the idea is this; Team X gets penalized on a bad call so later in the game the refs will call a bad penalty on Team Y to even things out.
This isn't game management. Game management is using the whistle as a deterrent, so as to establish a natural flow to the game without too many interruptions or too many infractions - maintaining that delicate balance in between so that players are playing hard, doing fringe activity, but not outright preventing scoring activity.
That balance is disrupted in the playoffs because players play harder and more competitively in the playoffs... so refs (and nobody really agrees to this) put their whistle away and allow teams to cheat. They actually FAIL at game management that fans start talking about them the next day. I repeat: this isn't game management but the failure to manage a game.
I like game management - the point isn't to call every penalty to see, but to keep teams from committing them in the first place through clear communication and establishing standards in the first period. This will make it so the game doesn't seem constantly interrupted by officiating (and their egos).
One thing I definitely don't want in the game is "by the letter of the law" legalism, which will make it so soulless and joyless that I'd rather watch paint dry. The human element is what makes things interesting, even if it's a wrestle for balance.
The point is that no one can ever make a set of rules that'll be universally adhered to, so the system gets tinkered with until there's equilibrium. Refs have been failing lately in the postseason (this year and for the last 12 - 15 years) where they've taken special teams out of the game.
