For Week 4 PPR fantasy football, current expert and model-based recommendations emphasize a few key players to start based on recent performance, injuries, and matchups. Top quarterback options include Josh Allen (BUF), Lamar Jackson (BAL), Justin Herbert (LAC), Jalen Hurts (PHI), and Drake Maye (NE), with Allen and Jackson leading projections for points this week.

At running back, injuries to some starters like James Conner and Najee Harris have elevated the value of backups like Trey Benson, Omarion Hampton, and Cam Skattebo. Start running backs who have a clear path to carries and receptions in PPR formats.

Wide receivers to strongly consider starting include players like Puka Nacua (LAR), Justin Jefferson (MIN), and Jaxon Smith-Njigba (SEA) who have favorable matchups and high target volumes.

Tight ends also present a surprising breakout in Week 4, but specifics depend on the latest projections and matchup analysis.

In summary, for Week 4 PPR starts:

• Quarterbacks: Josh Allen, Lamar Jackson, Drake Maye are top options
• Running backs: Look for opportunistic backs stepping in due to injuries; favored are those with receiving upside
• Wide receivers: Puka Nacua, Justin Jefferson, and Jaxon Smith-Njigba are prime candidates
