Well if he is committed then.... I don't know why more players don't become more committed to being better ball players if it is that easy.
He has not cracked a 5% walk rate since 2013 and thats assuming that 7.5BB% is average in the MLB. I don't know how someone can be so convinced that just because he wants to be a top of the lineup hitter and raise is walk rate 3% its a skill he simply does not have.
