The Dallas Cowboys continue to conduct a backup QB competition between Joe Milton and Will Grier as we head into the second preseason game.

While Milton may have a rocket arm, even Nolan Ryan didn’t cinch his Hall of Fame election until learning how to throw a changeup.

Joe Milton likely would have played every snap in the Dallas Cowboys’ preseason opener on Saturday if the second-year quarterback had not sustained a minor elbow injury late in the 31-21 loss to the Los Angeles Rams.
