Yup. There are no signs to steal any one describing it that way is being ignorant. At best Naylor trying to pick up Dingler's positioning, but the catcher can easily be feinting on that and the batter knows it, so I bet most batters aren't going to treat the information as actionable anyway. Naylor was almost certainly hoping to get in someone's head though, and if the Tiger's fell for it, that's their fault.
Not to mention that If he really was stealing anything, he certainly would have a more subtle system of tipping his hitter than waving has arms like a windmill. It was a good show and the booth fell for it.
