Count the Washington Redskins as another franchise welcoming new players and simultaneously giving others a pointy shoe to the posterior. The Redskins announced earlier today that they have signed receivers Trent Shelton and Roydell Williams. The ‘Skins also announced that they’ve released tight end Devin Frischknecht, wide receiver John Halman, defensive tackle Brigham Harwell, linebacker Ronnie Palmer, and offensive lineman Isaiah Ross. But the big name is Williams. He had a solid season in 2007 with the Titans, but broke an ankle during practice prior to the team’s playoff loss. By June, Williams still was struggling to make it back. He started training camp on the PUP list, received clearance to practice in August, and then was dumped from the roster. If healthy, Williams can be effective. He caught 55 passes for 719 yards in 2007, including a five-catch, 124-yard game at Houston on October 21.
