If any positives come out of this knee-jerk crackdown one might be the return of the legs tackle. But the only way that would work is if the ref rewarded such scything tackles by allowing the tackler to get to his feet and return to the defensive line before the tackled player plays the ball.
I used to enjoy watching a low tackle (performed by such players as Allan Thompson, Ian Martin, Randall, Vautin, Beaver etc) as much as a clever run. It's been missing from the sport for the past 20 years, and I welcome its return.
