We have finally arrived at the fantasy football playoffs, and what a wild ride it's been. Especially at running back, most fantasy owners would describe this season as a rollercoaster of emotions, but the ones who made it into the dance still have plenty of start-or-sit decisions to make and ups and downs to endure. Our Week 15 fantasy RB rankings for standard leagues will make your life easier, serving as a beacon of light in an otherwise-stormy landscape.No byes this week shout it from the rooftops! While that gives us more options by expanding our player pools, it also gives us more potential landmines. Of course, the top-20 backs are basically must-starts. There are varying levels, with Derrick Henry (@ Chargers in Week 15) and Christian McCaffrey (@ Seahawks) Michael Ojemudia Jersey clearly the cream of the crop, but no workhorse studs in the top 20 should be benched.That includes Miles Sanders (@ Bears), who exploded in Week 14 and now gets a Bears D that has surrendered 160.6 rushing yards per game over the past three weeks. It also includes Chiefs rookie Isiah Pacheco (@ Texans) the clear RB1 in Kansas City's offense, who netted 93 scrimmage yards last week but consider teammate Jerick McKinnon a plus-start, too. McKinnon put up seven catches, 112 yards, and two TDs in Week 14, and against Houston's last-ranked RB defense, there are plenty of yards to go around for him and Pacheco.WEEK 15 PPR RANKINGS: | | | | | They aren't nearly where we expected them to be 15 weeks ago, but Najee Harris (@ Panthers) and Jonathan Taylor (@ Vikings) are still easy RB1s with little competition, especially in these juicy matchups. Carolina has surrendered the sixth-most standard RB points this season, while Minnesota has allowed 125.6 rushing yards per game over the past five weeks. Other inconsistent backs with plus matchups include Alvin Kamara (vs. Falcons), Ezekiel Elliott (@ Jaguars), Brian Robinson Jr. (vs. Giants), and Zonovan Knight (vs. Lions).WEEK 15 STANDARD RANKINGS: | | | | Don't worry too much about tough matchups for guys like David Montgomery (vs. Eagles), Joe Mixon (@ Buccaneers), or Travis Etienne Jr. (vs. Cowboys). These guys are undisputed RB1s in run-first offenses, and that Melvin Gordon III Jersey volume gives them nice floors and potentially high ceilings, regardle s of opponent. The same would be true for Dameon Pierce, but an ankle injury will likely leave him on the sidelines, paving the way for Rex Burkhead and Dare Ogunbowale (vs. Chiefs) to have flex value.WEEK 15 FANTASY PICKS: | | Pierce isn't the only key RB dealing with an injury. Kenneth Walker III (ankle), Josh Jacobs (finger), Jeff Wilson Jr. (hip), and Damien Harris (thigh) all bear watching. Travis Homer (vs. 49ers) or DeeJay Dallas, if he's over his ankle injury, and Zamir White (vs. Patriots) figure to take over if Walker and Jacobs are out, respectively, but neither would be recommended plays in brutal matchups. Raheem Mostert (@ Bills) is also in a tough spot, but having the Dolphins' backfield to himself should lead to flex-worthy numbers. Harris (@ Raiders) would be worth a flex spot in standard leagues if he's back, but that backfield figures to be dominated by Rhamondre Stevenson (@ Raiders) regardle s.WEEK 15 DFS: | Some backs in committees like Aaron Jones (vs. Rams) clearly have more talent than their running mate (AJ Dillon, in this case) but get used in ways that frustrate fantasy owners. We'd still start Jones, but we'd probably shy away from the inconsistent Dillon. Wealso like Antonio Gibson (vs. Giants) in addition to Robinson, although Gibby is better suited for PPR formats. And don't hesitate to start both JK Dobbins and Gus Edwards in standard leagues against a Browns' defense allowing the second-most fantasy points per game to RBs.WEEK 15 DFS LINEUPS: | James Conner ( Jacob Bobenmoyer Jersey @ Broncos) gets downgraded due to a tough matchup in Denver, but Pacheco and McKinnon proved last week that the Mile High D isn't a brick wall. D'Onta Foreman (vs. Steelers) is in a similar situation against a Pittsburgh D that just allowed Baltimore to ama s 215 ground yards and a TD. We're more worried about him losing touches to Chuba Hubbard, who's received 31 carries in the past two games and generally looked better than Foreman last week. Cordarrelle Patterson (vs. Saints) is also in a tough spot and losing carries to Tyler Allgeier Brian Dawkins Jersey , but he always seems to find a way to produce. And don't sleep on D'Andre Swift (@ Jets) just because he had a down Week 14 against Minnesota. New York has surrendered 63 catches to receiving backs, so Swift could turn some targets into fantasy points even in standard leagues.If you're stuck with players ranked in the mid-30s or 40s, thoughts and prayers, but let's talk about upside, which should be in your consideration in a single-elimination setting. Devin Singletary and James Cook (vs. Dolphins) have higher floors and ceilings in PPR leagues in a game that could set a record for drop-backs. We're also intrigued by Rachaad White and Leonard Fournette (vs. Bengals) for the same reason, though neither receives enough carries to excite us in standard leagues. That's true for most backs below them in the rankings, as you shouldn't need to chance it with a backup in a middling matchup during a week with every team in action.Note: We'll be updating these RB rankings throughout the week, so check back for analysis and the latest player movement.
