The Giants.com crew breaks down the 21-6 loss to Dallas in Week 15 and looks ahead to storylines for Week 16:

John Schmeelk: The performance of the Giants' defense against the Cowboys on Sunday, especially considering the opponent and the injuries in the secondary, was probably the unit's best defensive output since it only allowed 20 points to the Chiefs in Week 8. Dallas managed only 328 yards of offense, and both of their touchdowns came on drives that started inside the Giants 30 (after an interception and a turnover on downs). Dallas only had two drives that went move than 45 yards for scores (both field goals), scored touchdowns on only two of five red zone drives, averaged only 4.2 yards per carry, and Dak Prescott was held to 217 passing yards. Dallas didn't have one play go for more than 20.

All of this was achieved with the secondary missing Adoree' Jackson, Darnay Holmes and Aaron Robinson. Alongside James Bradberry, the Giants had to play a group of reserve cornerbacks featuring an inexperienced Jarren Williams and special teams ace Keion Crossen. Logan Ryan and Julian Love had to help the group against one of the best collections of wide receivers in football: Amari Cooper, Michael Gallup, and CeeDee Lamb. In short, the secondary deserved credit in defeat.

Dan Salomone: The Giants' woes on offense continued with a 6-point performance against the Cowboys, tying their lowest output in the Joe Judge era. They have averaged just 11.8 points in their five games since the bye week and have thrown for fewer than 200 yards in five of their past six outings (202 in Week 12). Now, they could be starting their third different quarterback since that stretch began. Jake Fromm made his NFL debut late in Sunday's game, relieving Mike Glennon (the injured Daniel Jones was out for the third consecutive week) and entering the conversation to start in Week 16 at Philadelphia.

"We got to a point in the game where I wanted to see what Jake could do, point blank," Judge said before Jones was placed on injured reserve. "We weren't doing enough moving the ball otherwise, so I wanted to make sure I had the chance to see Jake and that will obviously open up a conversation about what we're going to do this week. We'll talk about it as a staff and we'll make the best decision for the team."

Lance Medow: If turnover differential is synonymous with wins and losses, then that's all you need to look at to explain Sunday's 21-6 setback against the Cowboys and the Giants' current three-game skid. New York matched a season-high with four turnovers against Dallas and, if you throw in a pair of stalled drives on downs, the Giants had six of their 10 possessions result in a strong negative outcome. It's virtually impossible to win a game under those circumstances - let alone remain competitive.

Over the past three games, the Giants' turnover differential is minus-6. They have seven turnovers and just one takeaway. In Sunday's game against Dallas, they had an interception returned to their own 13 and a fumble recovered at their own 46 – those drives resulted in nine first-half points – and a failed fourth down in the third quarter turned into a Cowboys touchdown for a combined total of 15 points. It's also no coincidence that the Giants are 3-2 when they win the turnover battle and 1-8 when they are no better than even.
