For me it’s his constant crying, or how it seems he usually is. Barking at the umpire from the dugout or on twitter pouting for his fellow players whose names have been thrown around in trade rumors and the uncertainty that comes along with it - “it’s NOT FAIR!”, as he would say. Well BOO HOO - Are you that soft? Turner WANTS to be a leader, and to me a leader leads. He does not whine or cry or make noise for the sake of being heard.
You know what else grinds my gears? Turner literally stands on the plate when he is at bat, or hangs over the plate and then makes absolutely no effort to get out of the way of any pitch resulting in numerous HBPs.
