Rams agreed to terms with FB Mike Karney on a three-year, $3.6 million contract. The deal includes $1.2 million guaranteed.
St. Louis has searched for a punishing lead blocker since Scott Linehan inexplicably waived Madison Hedgecock in-season two years ago. Karney, 28, should have something left in the tank. He's not much of a threat with the ball in his hands, but only turns 28 this July and was an All Pro in 2006. Karney is used to playing in a dome and figures to help Steven Jackson.
