I'm a little surprised to see LB Tracy White go, but he was released and they signed LB Danny Lansanah from the practice squad. White was the leading tackler on special teams the previous two seasons, but the special teams haven't been playing well the last couple weeks. If White isn't contributing there, then he doesn't belong on the roster because he's looked bad when playing on defense. Lansanah showed some promise during the preseason. Maybe he's a better all around player. Apparently GM Ted Thompson thought so.
