Dallas Cowboys owner Jerry Jones is very encouraged with his team and starting quarterback Dak Prescott despite suffering a 24-20 loss to the Philadelphia Eagles in their season opener on Thursday.In a game interrupted by lightning strikes and marred by Jalen Carter's early ejection for spitting on Prescott, the defending champions held off the Cowboys for a narrow win.Jones said he saw many good things from his group."I'm proud of this bunch," he told reporters. "If we get this kind of effort and we get this kind of level of play … we got a chance to be a good team."Prescott is coming off a difficult 2024 season, during which he played just eight games due to a hamstring injury. On Thursday, he completed 21 of 34 passes for 188 yards and no interceptions.There were a lot of question marks surrounding the quarterback and how me might bounce back after being off the field for so long. The three-time Pro Bowler did not play a single snap in preseason, but looked sharp on his return to action."I thought Dak (Prescott) may have played one of the best games I've ever seen him play," Jones said. "I just can't say enough about this effort. … I am encouraged."The Cowboys are coming off a 7-10 season, having missed the playoffs for the first time since 2020.There has been considerable attention surrounding the team in recent weeks, following the bitter feud between the team owner and Micah Parsons. The matter was resolved when Jones traded away the four-time Pro Bowl linebacker to the Green Bay Packers, receiving two first-round picks and Kenny Clark as part of the deal.The Cowboys registered just one sack on Jalen Hurts, though offensively, they didn't give up any.Dak Prescott opens up about CeeDee Lamb's performanceWhile the Cowboys' offense moved the ball effectively against the Eagles, they ultimately fell short. Uncharacteristically, Prescott's go-to receiver, CeeDee Lamb, had a couple of drops, which could have changed the complexion of the game. Prescott, though, said he still has plenty of confidence in Lamb's ability."It wasn't just those plays," Prescott said. "There's throws out there that I want back, but it's game one and he's a guy that makes those plays. He's going to make those plays."Lamb, though, accepted responsibility for the drops, saying:"Man, that's terrible. Honestly, I feel like I can't point no fingers at anybody else. I take full accountability and everything else that comes with it."Lamb led all receivers with 110 yards on seven catches.The Cowboys will hope for a better outcome next Sunday when they host the New York Giants.
