I, for one, like the rule. I like the ejections, and I like the way it has been called, even though some of my Alma Mater have been ejected this year (2 that I know of).
If we want to have a game to continue to officiate, this change in mind set *MUST* be made. There is nothing saying that football has to continue in prominence.
I am already seeing fewer players at the peewee level. Few kids, fewer parents letting their son's play football.
There are still kids who hit plenty high in high school. They are taught that from somewhere. I havent had to eject anyone yet (in 7 years of officiating I have only called targeting once, and that was before the ejection was in place).
So, that is my .02 worth. Keep it as it is.
