Different coaches have different styles. Some styles us parents agree with, others we arent so fond of.
Doesnt really matter though, cause bottom line, he's the coach and we are simply observers.
The lesson and important part here, is how you teach your son how to deal with it.
Most of the time, the athletes get it real quick ( they adapt, overcome, & achieve ), especially if we the parents, stand back a bit and watch from the side...... ( or out behind center field...or from across the street,..behind a tree,..etc.
)Best of luck and hang in there!
