I wouldnt be sure. Yes, the players should have some baseball IQ by now, but coaching and teaching never stops. Its as if they have never gotten clues to pick up on where a pitcher is going. I wouldnt lay all that on a HS coach. Until they hit MLB they can and should be coached on all things.at this age you can't coach mistakes like that, they should know better. I'm sure they talk about it all the time.......
