In some ways might it not help them to develop better technical players? No teams able to just hoof it forwards (which happens at every level and age group) so they'll actually have to practice keeping the ball on the floor. I'm sure they'll still head a ball when playing with friends etc so it's not like the skill of jumping for a ball and heading it will be totally lost. If there's a demonstrable risk of it damaging the long term health if kids head the ball (not sure what evidence there is, and whether it is based on the current balls or the hard ones that were used years ago) then it makes sense tbhMorons considering its a massive part of the game.
Mind cant hurt the Scots not like they are winning anything anytime soon.
