Martin Gramatica, signed last Monday after Parcells cut the enigmatic Mike Vanderjagt, kicked a 46-yard field goal with a second left Sunday to give the Cowboys a 23-20 win over the Giants and a two-game lead in the NFC East. "I've got to thank the Cowboys for giving me a second chance," said Gramatica, once a top kicker who had just one field goal in three games since 2004.
