So? Since baseball's inception, pitchers loaded up the ball, until that was stopped. For a long time, football players would go after opposing QB's heads, until they stopped allowing that. "They've always done it like this" is a stupid argument.
What's more, is the after the whistle crap is ILLEGAL. The officials just decide to "let them play" in the playoffs. And, to be honest, I don't mind ignoring ticky-tack stuff that occurs between the whistles. But how is not wanting to see a bunch of guys face-washing each other EVERY TIME the goalie freezes the puck "liberal minded bull####?" No offense, but maybe you are too ###-backward in thinking that the way things were done in "the good old days" was better.
