What about McAllister? I know he has injury concerns, but so does Springs. If we are bringing in someone for the 4th, then he should be a good fit as long as he doesn't want too much money. He will only be in on passing downs anyway so he may only see 15 to 20 plays a game.
Hopefully Springs' father will encourage Shawn to sign with the Cowboys, but if not, McAllister should be an option.
