Actually its Jerry Jones whose talking trash about the New York Giants.
Jerry Jones told fans at the Cowboys stadium:
y’all should come to that (Cowboys) stadium and watch us beat the Giants’ ass
The only response from the NYG is from Justin Tuck but it was short and sweet:
Because talk is cheap. Play the game.
Cowboys former tight end, who is now on the Giants, Martellus Bennett, that he is ill will toward his former team but nothing against Jerry Jones specifically.
