the stupidest thing they can do is get rid of him i dont have him as a teacher but what i have heard were only good things about him!!
I don't know why people think he is a bad teacher. I think he is a really nice teacher. So if you don't like him keep it to yourself.
Castelli is so cute I just want to give him a big hug. He is the best teacher and the best pitcher. He went pro for a reason.
