Very effective Vs what intended outcome.rowan wrote: But American football is all about yardage and even the most serious offenses are punished in this manner. No send offs. No shots at goal. & it is amazingly effective.
It's a game of stoppages anyway so the interventions matter less, but also despite there being loads of match officials (I don't know the number or what they call them) there are still crap loads of those yellow bean bags thrown into play in every game I've ever seen suggesting players offend all the time. And I'd contend players offending all the time doesn't suggest you're getting a desired outcome.
Also players will happily illegally slow play, remove/reduce a contest for the ball and so on in rugby when they know there's a sanction of loss of ball, 40-50m in territory and even 3 points against them, how does removing card sanctions help that scenario?
(For the avoidance of doubt I'm not genuinely asking for a response, I'm only suggesting your post is stupid)
