'This is just the start': Giants QB Jaxson Dart headlines NFL Week 4 rookie standouts

Adjusting to the NFL can be difficult for rookies, but each season, a few stand out almost immediately. Here are five from Week 4: 

New York Giants QB Jaxson Dart (first round)

Why did Dart (pick No. 25) sit behind QB Russell Wilson through the Giants' first three games? On Sunday, he led New York (1-3) to a 21-18 home upset over the Los Angeles Chargers (3-1). 

Per CBS, Dart became the first QB over the past 20 years to win his first career start against a team 3-0 or better. The last to do so was Marc Bulger with the Los Angeles Rams, then based in St. Louis, in 2002 (via CBS Sports' John Breech).

"It was just special to get the first [win]," Dart said in his postgame news conference. "This is just the start."

Dart will be without star wide receiver Malik Nabers after he suffered a season-ending ACL tear in Week 4. If the QB continues to establish himself as a dual threat, that would help the offense. Against L.A., he completed 13-of-20 passes for 111 yards and one touchdown and rushed for 54 yards and one TD on 10 carries.

New York Giants LB Abdul Carter (first round)

Dart's debut was the main storyline against the Chargers, but Carter's performance shouldn't be ignored.

Pro Football Focus credited Carter (pick No. 3) with a season-high eight pressures, including five QB hits. This contributed to Chargers QB Justin Herbert's struggles. He tossed two interceptions and posted a subpar 39.6 QBR, a season low.

With Carter and Dart flashing promise early, Giants fans should feel more optimistic about the team's trajectory. 

"The future is now," said Carter, a Penn State product, in a postgame news conference.

Las Vegas Raiders RB Ashton Jeanty (first round)

Jeanty (pick No. 6) breaking out was a silver lining for the Raiders (1-3) in Sunday's 25-24 home loss to the Chicago Bears (2-2). 

The former Boise State star rushed for a 64-yard TD late in the second quarter and finished with 155 yards (138 rushing and 17 receiving) and three TDs (one rushing and two receiving).
