The Dallas Cowboys went 30 years without drafting an offensive lineman in the first round. They might do it for the second time in three drafts Thursday night.

Blockers are among the needs after Dallas signed two free-agent guards last year and still finished second-to-last in rushing in the NFL.

If the Cowboys take a guard in the first round, it will be just the second time in franchise history. Right tackle is a question, too, after Doug Free had a bad year and became a part-time player alongside undrafted free agent Jermey Pernell.

Dallas also has needs at safety, defensive line and linebacker as it switches to the 4-3 alignment. And there's no established backup to injury-prone running back DeMarco Murray.
