I need to pick up a DL off of waivers (probably Kalimba Edwards) in order to fill in for Kevin Williams bye week. Should I:a) Drop Kevin Williams, who has been a major bust thus far. Or...b) Drop either Gus Scott or Kerry Rhodes, who both have more upside, imho. Scoring is pretty basic: 1 pt per tackle and pass defensed, .5 per assist, 3 per sack, 2 per forced fumble and fumble recovery, 4 per INT, and 6 per TD. Thanks!!!
