Dak Prescott might not have answered all of the Dallas Cowboys' backup quarterback questions, but the rookie gave the team a few reasons to believe he's ahead of schedule in his development.

Prescott completed 10 of 12 passes for 139 yards and two touchdowns in the first half of the Cowboys' preseason debut Saturday against the Los Angeles Rams. His two incompletions were both drops by his intended receivers.

The fourth-round pick from Mississippi State found wide receiver Dez Bryant twice on jump balls on Dallas' opening drive, including one for a 10-yard score. He capped the next drive with a 32-yard touchdown strike down the sideline to wide receiver Terrance Williams.

The only trouble of the evening came on his final drive of the night, as Prescott initially pushed the Cowboys out of field goal range by taking a delay of game penalty on 1st-and-20 and subsequently being sacked. But his third-down scramble for 14 yards helped set up kicker Dan Bailey for a 44-yard field goal.

Prescott was forced into the role as Tony Romo's potential backup when Kellen Moore suffered a fractured right fibula. Originally projected to be a developmental prospect in his first year, Prescott might end up serving a much more important role in 2016 if Dallas opts not to add an established veteran at quarterback.
