The problem is enforcement, not the rule.
Meanwhile, girls who follow the rules continue to lose spots and scholarships to players who replant. A friend's DD was recently granted a scholarship at a local D1. She clearly replants every pitch. How is it that she has been allowed to continue through the years of gold level ball and now into college as a replanter? The umps refuse to force these girls to comply (thanks OP for your honesty, I completely understand)... The problem has only got worse and will continue as Barnhill becomes a role model and a standard to many more youth and PC's.
Aside from replanting, you have Monica Abbott and a zillion other college pitchers allowing there drive plant to separate from the rubber before pushing off. Is this an acceptable rule to look over? My kid occassionally does the same thing and gets called for it instantly. Again another selectively enforced rule. It seems as if you are a very high caliber player you get the extra advantage of being able to "two step" and/or replant, but if you are playing B / low A level ball, you HAVE to comply with the rules.
It has gone on too long and is too deep to rewind. I'm sick of watching HS coaches spend countless innings complaining to umpires just to try and get a timely IP call to screw up some average pitcher just to gain a small hitting advantage (or advance runners) while she recalibrates.
For crying out loud just change the rule and we can all just move on! High level players can keep cheating and low level players can stop paying the price.
This is not a new problem. The administering associations should be ashamed of themselves for letting this go on so long.
