Calvin Hill, the patriarch of one of America's great sports families, was standing outside the Dallas Cowboys' locker room shaking his head in amazement after comparing rookie quarterback Dak Prescott to the 1971 version of his old teammate, Roger Staubach, who won a Super Bowl that season after taking over as Tom Landry's guy.

"Roger was 29," said Hill, adding, "and this kid is 23. Roger wasn't ready to play continually in his first year [in 1969]. Dak? I'm amazed at this young guy, amazed at his presence in the pocket."

According to ESPN, Hill was amazed at Prescott's ability in the game against the Philadelphia Eagles on Sunday night, when the quarterback spun left out of trouble in overtime and found a wide open Jason Witten in the end zone for the Cowboys' sixth straight win.

"Dak reminds me of Roger in terms of being able to extend the play," Hill said, "but he also reminds me some of [Tom] Brady in how he manages the game. I don't think Dak managed it well tonight, but [Jim] Schwartz is a really good defensive coordinator for Philadelphia. That front put so much pressure on Dak and yet he never lost his composure."

However, Prescott did not play a clean ballgame after he made some throws against Philly that looked like fourth-round throws. Even SB Nation said that Prescott was simply off all night. Fortunately, he was able to pull out his magic, completing all five of his passes in the extra session for 56 yards, including a 5-yard, game-winning touchdown pass to Jason Witten.

It's a good news for Dallas and NFL that the Cowboys still won despite Prescott's performance, proving that the team is a Super Bowl contender. When that happens, the league benefits in a big way.

"It's like the Yankees," Hill said. "There's so much passion around the country for and against them. The Cowboys are back, we have two young stars in Dak and Ezekiel Elliott, and that's good for the National Football League."
