"LaRoche prefers the education of the ballpark to school. Drake goes to traditional school only in the winter. He spent springs and summers with his father, and even as recently as this week, he was fully outfitted in a White Sox uniform and shagging fly balls, just like he did last season and the two previous with the Washington Nationals, who first allowed Drake to tag along."
And considering the money LaRoche has, the education that kid gets in the winter is probably better than the one most kids get who go to school far more often.
Also interesting from that article:
"Chicago-area radio host David Kaplan said Drake being allowed in the clubhouse was part of LaRoche’s deal to sign with Chicago for two years and $25 million before 2015, and the Twitter account of LaRoche’s company, E3 Meat, tweeted out a thumbs up emoji, followed by: “you are on to something.”
