But it's not "a problem" is it really?The FA Guidance on this has a couple of attempts for u8 and u9 and then an underarm throw. IIRC u10 and u11 non-competitive gives 2 attempts by the same player and then goes to the oppo. All about educating the players.
From then, u11 competitive games and all u12 and above are only one attempt as per LOTG. However, round my way, a lot of young refs don't give foul throws at all and as they never attend local RA meetings or get assessed, I end up suggesting they start giving foul throws. Hopefully a crackdown on this by the CFA and RA will help remove this problem.
