The Rams are getting meaner up front

The St. Louis Rams got meaner Friday when they reached agreement with Atlanta Falcons guard Harvey Dahl on a four-year deal, as reported by ESPN's Adam Schefter.

The move fills a void at right guard while giving the Rams what I would consider needed bite up front.

Dahl is one of those offensive linemen who gets under opponents' skin, the type teammates love and opponents love to hate. Dahl ranks third among NFL offensive linemen since 2008 in penalties for personal fouls and unnecessary roughness, according to ESPN Stats & Information. In 2009, he drew then-San Francisco 49ers coach Mike Singletary into a verbal spat during a game. Singletary later apologized.

Adam Goldberg had been starting at right guard for the Rams, but he was best suited, in my view, as the type of versatile backup every team can use. Goldberg, an unrestricted free agent, gave the Rams flexibility through his ability to play guard or tackle.

Dahl was undrafted out of Nevada in 2005. He spent time with the 49ers in 2006 before working his way into the lineup with Atlanta.

Our Scouts Inc. Insider report on Dahl reads, in part, that Dahl "gives Atlanta a competitive, try-hard blocker on the inside. He has excellent dimensions for the position and is an adequate knee bender, but has limited lateral range and change-of-direction agility."

Dahl isn't likely to challenge for Pro Bowls, but he's going to challenge the defender in front of him. He's going to play with attitude. Again, the Rams can use that dimension up front. They had it for a while in Richie Incognito, but his over-the-edge behavior on the field became untenable.

Matt Williamson of Scouts Inc. told me he thought the Rams would be fine turning over the right guard job to John Greco, a player Williamson considers vastly underrated. Greco probably has more talent than Dahl, but Dahl brings an edge the Rams can use on offense.
