One thing any player needs is good BP. Quite often in Little League a parent claims he throws great BP, some can, some not so. I had witness a dad throwing BP to a bunch of Little Leaguers and the dad nailed 3 kids right in the back.A number of kids said, : Man he really sucks, I am not hitting against him,” before being relieved for safety.
The other BP problem is the crazy dad who throws without a pitching screen. I have been hit one time ever, just because the ball went through an old pitching screen. I will not throw BP unless it is a 7 by 7 foot with a strong net.
I had witness one crazy dad throwing to a 6 year old who was really good , nothing but line drives. The dad was throwing with no L Screen, before long the dad took one off the shin and was on the ground yelling 4 letter words in pain
