"Tony Romo and NFL rushing king Emmitt Smith are at odds over whether the Dallas Cowboys have the mental toughness to beat the New York Giants in Sunday night's win-or-go-home game.

Smith suggested his former team lacks the fortitude needed to go to MetLife Stadium and capture the NFC East crown by beating a team it fell to 37-34 three weeks ago.

"Talent-wise, they have it," Smith told ESPN. "Leadership-wise, they have some good leaders. Do they have enough? Probably not. Can they go up to New York and be mentally tough in this situation? Jason (Garrett) has done a very good job of preparing the guys to be physically and hopefully mentally tough, but mental toughness is the one thing needed in games like this."
