History says Cowboys could keep inexperienced backup quarterbacks

OXNARD, Calif. -- The Dallas Cowboys' Twitter mailbag is ready.

In it we discuss:

Away we go:

@toddarcher: Let's see what he does Saturday against the Los Angeles Rams. Covering Jerry Jones long enough you learn not to buy stock in everything he says. Sometimes it's for effect, like hoping Jaylon Smith will play this season. Jones said the development of the young quarterbacks has him thinking of standing pat behind Tony Romo. It certainly sounds a little strange considering the Cowboys' record without Romo last season. Dak Prescott's arrow has been pointing up since camp started, but it's too difficult to know for sure if he can be the No. 2. It's a tall task for a fourth-round pick, or even a first-round pick in some cases. But let's go back in time for a second. In 2004, the Cowboys cut Quincy Carter in camp and had Vinny Testaverde as the starter. Despite Testaverde's age -- he was 40 when the season started -- the Cowboys went with Romo, who did not play a game as a rookie in 2003, and Drew Henson, who had been playing baseball, as the backups. The Cowboys were coming off a 10-6 season and a playoff appearance in Bill Parcells' first season, so it wasn't like that team had low expectations at the start of the year.

@toddarcher: To me the likeliest candidate would be Tyrone Crawford. He had a career-high five last season playing most of the season with a bum shoulder. If he can stay healthy, I think he has the best chance. Remember, Jason Hatcher had 11 sacks from the same position in 2013. DeMarcus Lawrence had eight sacks last season, but will miss the first four games because of a suspension. Benson Mayowa has two career sacks. There just isn't another player with a track record that suggests he will get more than eight. As for the total sacks, I don't see them getting more than 35 this season. Just once in the past six seasons have they had more than 35 (42 in 2011) in a season. That doesn't mean the Cowboys will have a poor season. In 2014 they had just 28 sacks and finished 12-4.

@toddarcher: If I were constructing a 53-man roster today, I would have Andy Jones on the team. I think he's been the better of the two receivers over Lucky Whitehead. The difference is Whitehead can return kicks and punts. Jones, so far hasn't. When you see Romo take an interest in an undrafted receiver like Jones, you know there's something there. Will he play a major role on the offense? Doubtful. But is he worth developing? Yes, especially when you consider Terrance Williams and Brice Butler are entering the final years of their contracts. Jones doesn't look like he runs fast or is particularly quick, but he gets open and can create some separation. He also has strong hands and doesn't let the ball get to his body.
