Week 1 FLEX Rankings News
Jalen McMillan, Tampa Bay Buccaneers
Tampa Bay Buccaneers wide receiver Jalen McMillan (knee) is competing for the No. 3 role on the depth chart, and his experience in the Bucs' offense gives him an early advantage over his teammates. Chris Godwin Sr. and Emeka Egbuka (toe) project as Tampa Bay's top two wideouts, leaving McMillan and Ted Hurst III vying for the next spot in the pecking order. The good news for McMillan is that Hurst is a rookie, which means his ascension into a meaningful role might be delayed as he adapts to NFL speed. On the other hand, McMillan has been in the NFL since 2024 and has 17 games' worth of experience (plus three offseasons) under his belt.
His familiarity with the system and his connection with quarterback Baker Mayfield go a long way, especially considering that McMillan averaged 10.4 fantasy points per game in PPR leagues as a rookie. Managers should expect McMillan to open the year as the Bucs' No. 3 wide receiver, which also puts him on the fantasy radar in deeper leagues. The 24-year-old is a matchup-dependent WR3/flex as it is, and he would jump into the WR3 tier on a consistent basis if Godwin or Egbuk were to miss time. As a result, McMillan should be added off the waiver wire in all 12+ team leagues.
Ryan Flournoy, Dallas Cowboys
Across 16 games in 2025, Dallas Cowboys wide receiver Ryan Flournoy recorded 40 catches for 475 yards and four touchdowns on 56 targets. Entering 2026, Flournoy remains behind star Cowboys wide receivers CeeDee Lamb and George Pickens, which may make it difficult for him to provide consistently fantasy-relevant production. However, Flournoy closed the 2025 season strong, recording 20 catches for 241 yards and two touchdowns on 27 targets across his final four games played.
The 26-year-old has also drawn positive buzz from both team personnel and Cowboys beat writers throughout this summer. When Dallas deploys three-wide receiver sets, the attention defenses are forced to give to Lamb and Pickens should open up the field for Flournoy. In leagues where he remains available, Flournoy profiles as a must-add stash for fantasy managers.
Tre Tucker, Las Vegas Raiders
Las Vegas Raiders wide receiver Tre Tucker had the most productive season of his career in 2025, recording 57 catches for 696 yards and five touchdowns on 92 targets across 17 games. While Tucker's numbers may not leap off the page, his statistical impact was limited by the offensive environment around him in Las Vegas, which was one of the NFL's worst in 2025.
Entering 2026, the Raiders have a new head coach and play-caller in Klint Kubiak, and two new quarterbacks in veteran Kirk Cousins and first overall pick Fernando Mendoza. Tucker could also remain the WR1 in a Las Vegas wide receiver room that features veteran Jalen Nailor and 2025 second-rounder Jack Bech as its other projected starters. Given the clear opportunity available to him with the Raiders, Tucker could be worth rostering as a depth piece in most fantasy formats.
Woody Marks, Houston Texans
Houston Texans running back Woody Marks appears headed for plenty of work in Year 2. Jonathan Alexander of the Houston Chronicle reported that Houston used Marks and David Montgomery nearly evenly throughout training camp, with the carry split expected to be close even if it doesn't land exactly at 50-50. Marks led the Texans with 703 rushing yards on 196 carries as a rookie, scoring twice on the ground while adding 24 catches for 208 yards and three receiving touchdowns.
He also looked sharp in his main preseason appearance, turning five touches into 43 yards with a 20-yard touchdown against Las Vegas. The Texans have talked about expanding Marks' work on third downs and in the passing game as well. Montgomery will have a significant role, but Marks looks like more than a change-of-pace option heading into the season.
