Fantasy football managers in IDP leagues have a lot to consider as Week 4 approaches, with standout performances and potential waiver wire additions in focus. Micah Parsons continues to impress despite being held without a sack for the second straight week, showcasing strong pass-rush metrics and playing time that make him a valuable asset. On the other hand, Trenton Simpson's dwindling snap share raises concerns about his role and production in the Baltimore Ravens' defense.

LB Jack Campbell of the Detroit Lions is a player to keep an eye on, having played 100% of defensive snaps in the absence of Alex Anzalone. Campbell's potential value in deeper leagues could extend if Anzalone misses more time due to injury. LB Devin Lloyd of the Jacksonville Jaguars is another player to monitor, likely to see increased playing time should Foyesade Oluokun be sidelined. However, Lloyd's role in the linebacker rotation may limit his fantasy upside to deeper formats.

In Las Vegas, LB Luke Masterson stepped up in a sub-package role due to Divine Deablo's absence, giving him relevance in deeper leagues if Deablo's injury persists. LB Anthony Walker Jr. of the Miami Dolphins seized a full-time role when David Long left the game, making him a prime waiver wire target if Long faces any downtime. Additionally, LB Pete Werner of the New Orleans Saints could step into a significant role if Demario Davis is sidelined, making him a viable option for IDP managers seeking linebacker depth.

The Carolina Panthers could turn to S Nick Scott if Jordan Fuller misses time, elevating Scott to a potential full-time safety role and presenting an opportunity for deeper league IDP owners. In Las Vegas, S Isaiah Pola-Mao saw increased playing time with Epps out, making him a viable option for leagues that value starting safeties. CB Cor'Dale Flott of the New York Giants thrived as the primary nickel corner in Week 3, showcasing his potential for another impactful performance in Week 4 after leading the team in tackles.

The waiver wire offers intriguing prospects like EDGE Josh Paschal of the Detroit Lions, who could see more snaps in the absence of Marcus Davenport. DI Tim Settle of the Houston Texans impressed with increased snap share among interior linemen, warranting consideration in DT-required leagues. Meanwhile, EDGE Nick Herbig of the Pittsburgh Steelers made a strong impact, playing extensively after Alex Highsmith's departure and delivering two sacks, making him a coveted pickup for teams in need of edge help.
