Troy Aikman has two concerning questions regarding Dak Prescott

Despite having the No. 1 offense in total yards per game and averaging 27.6 points per game last season, the Dallas Cowboys didn't even make the playoffs.

Dak Prescott posted MVP-caliber numbers, completing 67.3 percent of his passes for 4,552 yards and 30 touchdowns, but to no avail.

That's why team legend Troy Aikman has doubts about the team's ability to get much better, especially given Prescott's injury history.

In an interview with KDFW Fox 4's Sam Gannon, the former Super Bowl champion had two big questions for the Cowboys' QB.

Troy Aikman is worried about Dak Prescott's durability

“As Dak continues to get older, one: it's hard to stay healthy. So, will he make it through a full season? Will he make it into the postseason and be able to play?” Aikman asked Gannon. “And then on top of that: how long is he going to play at the level that he played at last year?”

The Cowboys' shortcomings were mostly due to their subpar defense. Per Aikman, that only made the season all the more frustrating, as Prescott may not have many more MVP-caliber campaigns left in him.

“I think the disappointing thing from the fans' perspective is that when you have a year like Dak had, and yet you don't even get to see that take place in January — you don't even make the postseason — that's a wasted year,” Aikman concluded.

Prescott hasn't been the most consistent signal-caller in the league, usually alternating good and bad seasons.

The Cowboys have an offensive guru calling the shots in Brian Schottenheimer, and keeping George Pickens in town will certainly help Prescott's case.

That said, it will all be futile if they can't get stops on the other side of the field, which is why they might be better off using their two first-round picks to add talent to multiple areas of need instead of trading up to get just one player.
