Is drafting a quarterback an option?

The Cowboys are committed to Tony Romo.

He has two years remaining on his contract and if he has a strong 2012 season, the team is open to giving him a new contract. There are no signs the Cowboys would even draft a quarterback, especially with the team signing Kyle Orton in free agency this spring to become No. 2 on the depth chart.

Of course, the Cowboys have Stephen McGee, the third-string quarterback, who has struggled at times to develop.

But with every season, NFL teams are looking to improve every position on the roster. Jason Garrett has said it's good to have competition at every position.

Should drafting a quarterback in the middle rounds -- the Cowboys have two fourth-round picks -- be an option?

We look at five QB possibilities:

Brandon Weeden: His age, 28, scares some NFL teams, but that age for the two-year starter from Oklahoma State gives him an advantage because he's more mature than some quarterbacks.

Russell Wilson: The biggest problem with Wilson is height. He's 5-10 5/8, but the 23-year-old makes plays. In his senior season at Wisconsin, he completed 72.8 percent of his passes and threw 33 TDs and just four INTs.

Case Keenum: The Abilene, Texas, product was a four-year starter at Houston. He did a nice job of making throws out of the pocket and reading defenses. His pocket awareness is a concern, but that can improve.

G.J. Kinne: A Gilmer, Texas, product who transferred to Tulsa from Texas. Kinne battled a knee problem his senior season but started 13 games for Tulsa. He finished the season with 28 TDs and 12 INTs. One of Kinne's weakness is his average arm strength.

John Brantley: Tim Tebow's backup at Florida is athletic and can make all the throws necessary, yet isn't very accurate. Brantley completed 60 percent of his throws his senior season with 11 TDs and seven INTs during an injury-filled senior season.
