I'm totally in favor of this. I hate these "Superman" tackles where the defender goes flying through the air hoping that the force of his blow will knock the ball carrier off his feet. he can miss or hit a glancing blow the ball carrier can bounce off. Either player is more likely to b injured with this flashy but stupid technique.
I remember when Danny Parkins had a Noon show here and insisted that Dick Butkus, (who played before he was born), "made his living on helmet-to-helmet tackles". I went to You-Tube and watched three Butkus highlight tapes which must have been from different season sicne there were no repeats. I didn't see a single helmet-to-helmet hit. Butkus led with his shoulder, arms out, gained control of the guy and then drove him backwards or threw him to the ground. he was a rough, tough guy but he was a textbook tackler.
Remember G-Rob having his players throw uppercuts? Jeesh...
