I have heard a lot of people say that Khaseem Greene and Arthur Brown are too small to play MLB. My question is why? Brown is 6' 241lbs and Greene is 6'1 242lbs. That is almost exactly the same size as Manti Teo who everyone agrees can and will play MLB.
Patrick Willis 6'1 242
Navorro Bowman 6' 242
So again, why are they "too small" to play MLB?
