Fantasy Waiver Wire Week 4: 5 to add, drop, buy low, sell high

• Add Jamaal Williams: D’Andre Swift played through injury and Williams managed 20 carries. Now Swift will miss some time, leaving even more opportunities for touches.
• Cut Mecole Hardman: The Kansas City Chiefs have used more two-tight end sets this season compared to last, and some backup wide receivers deserve more playing time.
• Sell High on Dameon Pierce: The Houston Texans have only used Pierce in typical running situations, but they will see fewer of those once the schedule gets more difficult.

5 PLAYERS TO ADD

1. RB Jamaal Williams, Detroit Lions

Williams continued to lead the Lions in carries despite D’Andre Swift presence. Swift suffered a should sprain, which isn’t expected to require surgery, but could cause him to miss some time.

• Williams ran the ball 20 times for 87 yards and two touchdowns while Swift posted seven carries for 31 yards.
• Swift continued to dominate the passing-game work, seeing most third downs, half of the two-minute drill and plenty of routes run on early snaps.
• Williams continues to take all of the goal-line snaps and much of the short-yardage work.
• Swift’s ankle injury limited him in practice all week, which could be part of the reason he’s not touching the ball as much. Typically, if someone is limited due to health reasons, they aren’t on the field as much and touch the ball on a higher percentage of snaps rather than staying on the field a lot and not touching the ball.
• Even when Swift is back and healthy again, Williams likely isn’t going away — at least not in short-yardage situations.
• Williams is should be started while Swift is out but remain a borderline starter, or at least a flex play, in the right matchups when Swift returns.

2. RB Khalil Herbert, Chicago Bears

David Montgomery suffered an ankle and knee injury early in the first quarter and was quickly ruled doubtful to return. Herbert became the Bears' lead back and dominated throughout Week 3.

• He ran 20 times for 157 yards and two touchdowns while catching two passes for 12 yards.
• Herbert and Trestan Ebner shared the snaps early on, but Herbert took more of the workload after playing well. He played 16 snaps to Ebner’s 13 in the first half but dominated the snaps in the second half, 22 to two.
• The second-year back would be the clear starter for as long as Montgomery is out.
• Montgomery was declared day-to-day in head coach Matt Eberflus’ post-game press conference.
• Herbert should be a waiver wire target regardless of Montgomery’s health. His rushing performance was Chicago’s best so far this season, and he could see more playing time even when Montgomery is healthy.

3. WR Romeo Doubs, Green Bay Packers

The Packers were hurting at wide receiver in Week 3, which helped Doubs lead the team in targets, receptions and receiving yards.

• Sammy Watkins landed on injured reserve earlier in the week with a hamstring injury and will miss at least the next three games.
• Christian Watson missed this game with a hamstring injury but could be back as soon as next week.
• Doubs is clearly ahead of Randall Cobb on the Packers' receiver depth chart, so he should remain second at least for the next three weeks.
• With more performances like this, he could become Green Bay's new No. 1 receiver.
