There is no question grade based is wrong. Let’s face it, if it was right, the other 6 sports would use it also. A lot of parents take advantage of it being wrong and hold Johnny back a year. Give Johnny the advantage over the other little kids. The other 6 sports they can’t give Johnny the advantage. In those sports, Johnny has to do it on his own. Johnny has to practice and play well for playing time, just like everybody else. No mommy and daddy taking advantage of a flawed system in those sports. This is the truth and everybody knows this.
