Aaron Wilson, reporter: The Ravens just upgraded their front seven in a major way with the acquisition of Pro Bowl pass rusher Elvis Dumervil. It's a five-year contract with a maximum value of $35 million, including an affordable first-year salary cap figure of $2.5 million as he'll make $8.5 million in the first year of the deal. Dumervil is a relentless defender who has combined for 37 sacks in the past three seasons with 10 forced fumbles during that span. Between Terrell Suggs and Dumervil, the Ravens should be able to generate some serious heat on the quarterback. Dumervil is 29 and still in his prime after registering 11 sacks last season. At a compact 5-11, 260 pounds, Dumervil has a strong spin move, bull rush and enough speed to finish plays. Of the available pass rushers, he was the lone one on the right side of 30. By adding Dumervil to go with Chris Canty and Marcus Spears, it should help offset the offseason losses of inside linebacker Ray Lewis to retirement and free safety Ed Reed (Houston Texans), inside linebacker Dannell Ellerbe (Miami Dolphins), outside linebacker Paul Kruger (Cleveland Browns), cornerback Cary Williams (Philadelphia Eagles) and cutting strong safety Bernard Pollard, who has since joined the Tennessee Titans. After sustaining heavy losses to the roster, Dumervil represents a big piece for a new-look defense.
