I see an issue, a current 2019's will want to send their grades (in June) to the coaches who've had their eye on them. Is the player wrong for sending the grades he is proud of, does the coach who opens the email have to worry about being in violation.

There has to be some things that are allowable.

Then again how about that 6'1" 2020 who has always worked hard to be accelerated in the STEM core courses and took HBio or HChem or HAlg2/Trig, Those classes are great barometers of a students future STEM achievements. A coach doesn't have to wait to see how that player will pan out That Freshman has the same core course as a Jr. That freshman knows where their future path lies.

Sure it is easy to say all or none, but I was taught the easy way isn't always the right way.
