SPELLING DOOM: Outside linebacker Elvis Dumervil was one of the camp standouts on Friday. He showed great burst off the line of scrimmage and seemed to be in the backfield on every other play, sometimes splitting a double team to get there. At one point, he abused rookie Rick Wagner, who was subbing in with the first-team offense at left tackle, on consecutive plays. He dusted rookie tackle David Mims on another. With Dumervil, fellow outside linebacker Terrell Suggs and defensive linemen Haloti Ngata and Chris Canty rushing against an offensive line that was missing three regulars, quarterback Joe Flacco hardly had time to take a three-step drop by the time the pocket collapsed around him. We have a long way to go until the sacks count, but Dumervil and Suggs appear to be as good as advertised.
