Middle infielders do that countless times a day across the league. Villar has been pretty darn mistake free all year. So no, he isn’t really that guy this year. However because of 2016 he will always be assumed as that guy whether he makes those mistakes once a day or once a year. It isn't just on defense. Sometimes its something like not running out a long fly and ending up on 2nd when he should have been on 3rd. And yes, it's not always just him, Shaw has had a few untimely errors this year. But guys like Hader and Shaw more than compensate in overall production.
