Chris Berman breaks down why the Cowboys have been winning so often this season and how far Dallas can go. (1:01)

The New York Giants and Dallas Cowboys have seen each other once before. But not in their current forms.

It has been almost three months since they met in the season opener in Texas. A lot has changed since then, beginning with Cowboys running back Ezekiel Elliott and quarterback Dak Prescott. They were rookies playing in their first NFL regular-season game when the Giants beat the Cowboys in Week 1. Now they're both potential MVP candidates.

Dallas (11-1) also hasn't lost since the Sept. 11 opener. Here is what they look like now, with six Cowboys to watch on Sunday against the Giants, courtesy of ESPN NFL Nation Cowboys reporter Todd Archer:

OFFENSE

QB Dak Prescott: In the last two games Prescott has relied more on his legs to make plays, and not only on designed runs. He has 14 runs in the last two games for 76 yards and a touchdown. As a passer, Prescott is coming off a season-low 139 yards on 12-of-18 passing against Minnesota. He had open receivers but did not make the proper reads at times. But what separates Prescott from most rookies is he will not make mistakes -- he has thrown only two interceptions on the season.

RB Ezekiel Elliott: He is a much different back from what the Giants saw in the opener when he had just 51 yards rushing. Entering that game, Elliott had only seven carries in the preseason and was still getting a feel for the Cowboys’ zone scheme. He learned it quickly. Elliott has just one 100-yard game in his last six outings, but he has had at least 86 yards in each of those contests. He just wears teams down with his physical style. The Cowboys' plan against New York in this week's rematch needs to be better against the Giants' big front than it was in Week 1, which will help Elliott make plays on the edges.

TE Jason Witten: Don’t get fooled by the fact that he did not have a catch or target last week against Minnesota; Witten remains a valued part of the Cowboys' passing game. He was open against Minnesota, but Prescott went elsewhere with the ball. He might not stretch the field the way Ladarius Green did last week for Pittsburgh, but the Giants have had trouble with Witten over the years. He remains a chain-mover and is also a key part of the running game with his work on the edges.

DEFENSE

CB Anthony Brown: The rookie started in the base defense over Orlando Scandrick last week, with Cowboys coach Jason Garrett saying Scandrick has been slowed by a foot injury. A sixth-round pick, Brown has had to play a number of roles in the secondary because of injury, but he has performed well. Teams have taken shots deep on him, and he has responded most of the time. But there is no question Eli Manning will look at him if there is a matchup with Odell Beckham Jr.

DE DeMarcus Lawrence: The Cowboys have 23 sacks on the season, but Manning does not give defenses much of a chance to get to him considering how quickly he gets rid of the ball. Lawrence did not play in the Week 1 meeting between the Giants and Cowboys because of a suspension, but he is the Cowboys' most dangerous edge rusher even if he has just one sack on the season. Lawrence is more about power than speed, but he can close the edge quickly. While he might not get to Manning, he has to at least affect the veteran quarterback to give the Dallas secondary a chance against a wide receiver corps that might be the best the Cowboys have seen all season.

S Barry Church: He will be in his second game back from a four-game absence due to a fractured right forearm. The Cowboys brought more pressure than normal with Church back in the lineup against the Vikings. He leads the Cowboys in interceptions and has their most recent: Oct. 16 at Green Bay. He is also a sure tackler and has a knack for finding the ball. Church brings a calming influence to the Dallas secondary, which might be needed in a big way on Sunday.
