Connie Mack and John Shibe arranged for McNair to serve as an usher so that he could watch his team play.

McNair said that he had great difficulty directing fans to their seats, so he ultimately took off his badge and sat in an aisle to watch the games.

Manager Jimmy Dykes helped him to relax and to forget about errors after they happened, which led to better overall fielding.
