Fantasy Football Playoffs FLEX Rankings (Weeks 15, 16, 17)

Fantasy Football Playoffs FLEX Rankings Outlooks

Blake Corum, Los Angeles Rams

Los Angeles Rams second-year running back out of Michigan, Blake Corum, dominated once again in Week 14, rushing for 128 yards on 12 carries (10.7 yards per carry) and two touchdowns in the Rams' 45-17 rout over the Arizona Cardinals. Corum is one of, if not the best, fantasy football handcuff right now and is a must-add off the waiver wire if available in your leagues. The Rams' offense ranks fourth in the NFL, averaging 29.2 points per game, and Kyren Williams, the Rams' lead running back, has also been solid in 2025 but has lately been giving way to Corum to help keep him fresh for the NFL playoffs.

Still, Rams coaches have expressed interest in keeping both involved, and Corum is no joke, averaging 5.45 YPC on the season. Corum remains an RB3/Flex consideration in leagues with multiple flex spots or 14 teams or more. On the season, Corum has rushed for 550 yards on 101 attempts with four touchdowns. Up next for the Rams is a big NFC clash against the Detroit Lions.

Troy Franklin, Denver Broncos

Denver Broncos wide receiver Troy Franklin has operated as the team's No. 2 wide receiver opposite Courtland Sutton for the vast majority of the season. However, his role in the offense has decreased lately, beginning in Week 13 against the Washington Commanders. The second-year wideout played 37 offensive snaps in that game, his lowest all season at that time, but his 68.8% route share still aligned with his season average of 71.6%. Both marks plummeted in the Week 14 win over the Las Vegas Raiders, as his snaps were cut in half to just 19 and his route share dipped to a season-low 39.5%.

Rookie third-rounder Pat Bryant has seemingly overtaken him as the No. 2 option opposite Sutton. After leading the Broncos in targets for most of the season, Franklin's role has been cut back due to his inconsistent hands and limitations as a run-blocker. He profiles as a low-ceiling flex option heading into Week 15 against a tough Green Bay Packers defense.

Darnell Mooney, Atlanta Falcons

Atlanta Falcons wide receiver Darnell Mooney failed to deliver once again with fellow receiver Drake London (knee) missing Week 14's 37-9 loss to the Seahawks, logging just one catch on four targets for six yards. The 28-year-old nearly had a touchdown catch, but stepped on the sideline before coming back inbounds to make the reception, nullifying the score. After a 64-catch season in 2024, accumulating nearly 1000 yards (992) and five touchdowns, it has been a season to forget for Mooney, now with just 22 catches for 329 yards and one score with just four games to go.

London was a DNP on Monday, so he could miss another contest, but it will likely be a boon to Kyle Pitts Sr.'s stats, not Mooney's. Week 15 brings a matchup with the Buccaneers on the road on Thursday night, against a Tampa Bay pass defense that is middle of the pack in terms of fantasy points allowed to opposing wide receivers. The veteran will likely be a risky WR4/Flex option in what will be the first round of the fantasy playoffs for most managers.

Darren Waller, Miami Dolphins

Miami Dolphins tight end Darren Waller has not looked the same in two games since his return from a stint on Injured Reserve for a pectoral injury. In the last two contests, Waller has three receptions for 60 yards and no touchdowns on six targets. The 33-year-old veteran played only 37% of the snaps in the Week 14 win over the New York Jets on Sunday, which was down from 47% in his return in Week 13. Not only did he see fewer snaps, but he was outsnapped by both Greg Dulcich and Julian Hill at the position.

Waller had one catch on three targets for 13 yards and added one carry for four yards versus the Jets. After coming out of retirement to play for Miami, he scored four touchdowns in his first four games. It's possible that Waller needs some time to get back up to speed, but fantasy managers can't afford to wait. He will be a risky, touchdown-dependent TE2 streamer in fantasy in Week 15 versus the Steelers, especially if Dulcich continues to be involved.
