After a very sluggish offensive start, a spark of life was shown by the Giants with 2:30 remaining in the first half of play.
Cruz stopped on a dime to avoid defensive back Antonio Cromartie and took off down the sidelines for a 99-yard touchdown.
Cruz has been one of the big surprises in the league this season. After starting the season as a backup, he has emerged as one of the best receivers in the league with 1,194 yards this season.
The score put the Giants up 10-7 heading into halftime after a missed field goal by the Jets as time expired.
There was a lot of exchanging of words among players prior to this game. Most of the trash talk centered around cornerback Darrelle Revis.
Revis wasn't around this 99-yard touchdown, but the Giants' players are probably laughing right now.
The Giants need to win this week against the Jets and next week against the Dallas Cowboys to take home the NFC East title.
In the 25 plays prior to the 99-yard touchdown the Giants managed just 83 yards.
This spark of life at the end of the half could be the momentum shift the team needed to get things rolling.
