Can Seahawks get last laugh with Barron?

The Seattle Seahawks have continually churned their roster along the offensive line, finding starter Breno Giacomini and other contributors that way.

Alex Barron becomes the latest addition after the Seahawks announced agreeing to terms with the veteran first-round choice Tuesday.

Barron, chosen 19th overall by St. Louis in 2005, generally impressed while working against rookies during Seattle's recent minicamp. He was inconsistent and prone to penalties with St. Louis. The Rams traded him to Dallas. Barron spent last season on injured reserve with New Orleans.

I'll resist the temptation to dismiss Barron's signing given Seattle's ability to run the ball last season with a patched-together offensive line. For example, Paul McQuistan was at left tackle last season when the Seahawks ended San Francisco's 36-game streak of allowing no individual 100-yard rushers.

So, go ahead and chuckle at Seattle for making a small bet on Barron, but it's no shock if Cable gets the last laugh.

Barron gives the Seahawks seven offensive linemen drafted by other teams. That includes choices from every round but the sixth (and two from the fifth). The chart shows drafted linemen on the Seahawks' roster, ordered by draft slot. Shading identifies players chosen by Seattle.

The chart does not show undrafted players, including contributor Lemuel Jeanpierre.
