Countdown to Combine: Green Bay Packers offensive line

INDIANAPOLIS -- We have arrived at the NFL scouting combine, which means it's time to wrap up our look at the Green Bay Packers' needs by position this offseason and which prospects general manager Ted Thompson might be taking a closer look at during workouts and interviews this week.

Here are the previous installments:

Feb 9: Defensive line

Feb 10: Linebackers

Feb. 11: Cornerbacks

Feb. 12: Safeties

Feb 13: Quarterbacks

Monday: Running backs

Tuesday: Receivers/tight ends

The series wraps up with the offensive line:

Why the Packers might need help: Even if the Packers re-sign right tackle Bryan Bulaga, and that's a big if, they still need help at tackle. They finished last season with JC Tretter as their No. 3 tackle, and Tretter is probably better suited to play inside at guard or center. Tretter went into training camp last season as the starting center but lost the job when Corey Linsley took over after Tretter sustained a knee injury in the preseason. Linsley played so well that the Packers plan to stick with him. They should get back Don Barclay, who missed all of last season with a knee injury, but Barclay is probably better suited as a utility man than a starter.

Offensive linemen the Packers should be watching: Both Mel Kiper Jr. and Todd McShay have five tackles going before the Packers pick at No. 30 in their most recent mock drafts. And they're the same five tackles: Iowa's Brandon Scherff, Pittsburgh's T.J. Clemmings, Miami's Ereck Flowers, LSU's La'el Collins and Stanford's Andrus Peat. Texas A&M's Cedric Ogbuehi is probably next on the list followed by Oklahoma teammates Daryl Williams and Tyrus Thompson.

Draft priority (low, medium or high): Medium. Just like at receiver, the priority level would shift to high if Thompson can't -- or decides not to -- re-sign Bulaga.
