It's beginning to look like the Panthers are out to sign every guard they can find.

They added another Friday, signing unrestricted free agent Milford Brown, who is 6-foot-5 and 330 pounds. Contract terms were undisclosed.

Brown's signing comes on the heels of the team's agreement with another giant guard, Toniu Fonoti, on Tuesday, adding to the impression that Carolina wants to get bigger along the line and exploit the power running game.

Brown, 28, has played with Houston, Arizona and St. Louis over six seasons. He had 16 starts over four seasons with the Texans, then started 12 games for the Cardinals in 2006. With St. Louis in 2007, Brown started nine games at left guard, four at right tackle and two at right guard. The Panthers like linemen with that kind of versatility.

In addition to these two, Carolina has loaded up at the position with Keydrick Vincent and a likely shift of Travelle Wharton from tackle. Geoff Hangartner also returns. Expect the O-line, which is likely to be bolstered by an offensive tackle in the draft, to have a completely different look this fall.
