Here's a look at some players that should take priority if you're looking to pick up some reinforcements from the waiver wire.
Khalil Herbert, RB, Bears: He rushed 20 times for 157 yards and two touchdowns as he replaced an injured David Montgomery. With two good matchups coming up, Herbert could prove to be very useful.
Isaiah McKenzie, WR, Bills: McKenzie is in a good spot, playing the slot for a good Bills offense, but he hadn’t produced a good fantasy score until Week 3. He caught seven passes for 76 yards and scored. The Bills have a good matchup for wideouts against the Ravens in Week 4.
Romeo Doubs, WR, Packers: The preseason darling had a breakout performance, catching all eight of his targets for 73 yards and a touchdown. He's caught at least two passes in each game, but Week 3 was a big day and he could continue it with Green Bay needing someone to step up in the WR corps.
Josh Reynolds, WR, Lions: Amon-Ra St. Brown is dealing with an ankle injury and Reynolds caught six passes for 96 yards to lead the Lions in Week 3.
Tyler Boyd, WR, Bengals: He's got a pretty good history when he gets an opportunity to contribute. Boyd has scored in two of three games so far and has shown he can break off chunks of yards.
Josh Palmer, WR, Chargers: Still available in a lot of leagues, he built off his good Week 2 by catching six passes for 99 yards in Week 3.
David Njoku, TE, Browns: Tight end is a tough position to fill. So when you see a player not on a lot of rosters catch nine passes for 89 yards and a score, you might as well give him a shot. Cleveland has two good matchups for tight ends coming up (Falcons in Week 4, Patriots in Week 6).
Laviska Shenault, WR, Panthers: His season debut was electric as he caught two passes for 90 yards, including an impressive 67-yard score. It won't be like this weekly, but players with upside and the ability to score quickly should have a place on your roster.
DeVante Parker, WR, Patriots: With Jakobi Meyers out, Parker led the Pats with 156 yards on five catches. Before Sunday, Parker had just four targets, but his showing against the Ravens should get him more opportunities.
Russell Gage, WR, Buccaneers: He led the Bucs with 12 catches on 13 targets for 87 yards and a touchdown. Mike Evans will be back from suspension, but the oft-injured Julio Jones and Chris Godwin give Gage some value.
Zay Jones, WR, Jaguars: Jones isn't the type of player you'll want to plug and play right away, but he may be worth adding to your bench. He's been targeted at least three times in every game and caught 10 passes for 85 yards and a touchdown in Week 3.
Mack Hollins, WR, Raiders: Hunter Renfro missed Week 3 and Hollins ended up getting more action, especially late in the game. Don't expect too much from him, but he could be serviceable if you need depth.
