The New York Giants did some good things in their 13-10 loss to the Minnesota Vikings in their preseason opener Saturday. The Giants have been linked to veteran running backs like Najee Harris, but if Singletary plays the way he looked Saturday, they won't need to add another back. Singletary made the game's biggest play, a 40-yard catch and run on a screen pass that turned third-and-23 into a first down in Vikings territory.
