Dallas Cowboys quarterback Dak Prescott is less than two hours away from becoming the first rookie QB to start a playoff game for the franchise in today’s divisional playoff game against the Green Bay Packers.

He’s looking to extend his extraordinary first season, one in which he broke several NFL records and led his team to a 13-3 record during the regular season and first-round bye in the playoffs.

In a recent interview, Dak’s brother, Tad, described what he goes through while watching his sibling start as the Cowboys’ starting quarterback.

“I don’t know if I’m excited or thrilled until there’s four zeroes on the clock and the game’s over and we have a W,” Tad said, according to DallasNews.com. “When he scores, if the camera could find me, I’m probably the one going craziest in the stadium. If there’s a turnover or something goes bad, I’m the one sitting there with my hands on my face, tugging on my necklace. I’m an emotional wreck for a football game, especially close ones. The blowouts are fun but [tight] games like the Eagles, Minnesota, they’re the ones I’m locked in.

“I don’t care if we’re best friends, I don’t want you talking to me right now, just let the game play out and then we can talk about it afterwards.”

Dallas will host Green Bay from AT&T Stadium for a 4:40 p.m. ET kickoff on FOX.
