NFL draft preview: Linebackers, defensive line

Are middle linebackers underrated?

The No. 1 need in the Vikings' front seven is smack dab in the center at middle linebacker.

E.J. Henderson, who turns 32 in August, remains unsigned. His heir apparent, Jasper Brinkley, is coming off hip surgery that wiped out his entire 2011 season. And the other options include newly signed Marvin Mitchell, who has two career starts, and moving Erin Henderson, which would then create a hole on the weak side.

The Vikings won't address the position in the first round. But fortunately for them, it's well established that teams don't have to spend a first-round pick to acquire a starting-caliber middle linebacker.

The Vikings don't have to look too far for shining examples of this NFL trend. E.J. Henderson, who started 105 games for the Vikings, was a second-round pick (40th overall) in 2003. And, better yet, linebackers coach Mike Singletary went from the 38th overall pick of the Bears in 1982 to arguably the best middle linebacker in NFL history.

A year ago, the first inside linebacker wasn't taken until the third round, when the Broncos took North Carolina State's Nate Irving 67th overall. This year's crop is significantly better and could see its No. 1 prospect, Boston College's Luke Kuechly, go in the top 12.

As for the Vikings, a player to watch at the top of the second round (35th overall) is Alabama's Dont'a Hightower. He's a 6-2, 265-pounder with strong instincts, athleticism and tackling skills. Whether he's fast enough to handle the coverage responsibilities in the Tampa 2 would be the primary concern in taking him.

Like a lot of college middle linebackers, Kendricks doesn't enter the draft as a hot prospect. He's projected by some as a third-round selection.

The Vikings have nine picks in Rounds 2 through 7, so don't be surprised if they use one of them on a guy who plays the most underrated of all the front seven positions: middle linebacker.

Today is Day 6 of the Star Tribune's position-by-position preview of the NFL draft April 26-28 in New York City.

Today: defensive line and linebackers

The defensive tackle has exceptional quickness and a knack for making big plays. Cox plays with high energy and has eye-opening athleticism for a guy who's 6-4 and 298 pounds. He should be able to start from Day 1 but also has ample room for growth.

Ever seen a 346-pound beast run the 40-yard dash in under 5 seconds? The folks at the NFL combine did. Now NFL teams have to weigh Poe's combine explosion vs. his pretty ordinary 2011 on-field performance.

An instinctive 6-3, 242-pounder with a knack for being around in the right place at the right time. He also ran a 4.58 40 at the combine. With his stock rising, Kuechly could end up at Seattle with the 12th overall pick.

A no-brainer pick if still available past Round 2, Curry understands leverage and plays with nonstop effort. He'll likely never be a Pro Bowler but could be an impact player for a long time if used right.
