The Browns will pursue two of the biggest-name pass-rushers in free agency in Baltimore’s Paul Kruger and Detroit’s Cliff Avril, league sources said. They’re also likely to go after Raiders defensive tackle Desmond Bryant and Cardinals linebacker Quentin Groves, according to sources. Teams can begin negotiating with other teams’ free agents at 12:01 a.m. Saturday, and can begin signing them Tuesday. The Browns have needs at quarterback, tight end, linebacker and cornerback. Kruger, who helped the Ravens defeat San Francisco in the Super Bowl last month, will be one of the most sought-after pass-rushers on the market if the Ravens don’t re-sign him by Tuesday. A second-round pick of the Ravens in 2009 out of Utah, Kruger (6-4, 270) had nine sacks in five starts at outside linebacker last season, and added 4.5 in the playoffs. Kruger, 27, could command as much as $9 million per year. The signing of Kruger would not only bolster the Browns but weaken their AFC North foe. The same would go for players such as Steelers receiver Mike Wallace and cornerback Keenan Lewis if the Browns go that route.
