​We shouldn’t be surprised that Week 2 was a mediocre one for backup RBs, as it was a mediocre week for offenses overall. There are only a few backups who have flex potential at the moment, as several players who were expected have key roles have thus far underachieved. Here are the 10 backups who must be rostered, with a second list at the bottom of those who can be added in deeper formats.Kyle Monangai, Bears (82% rostered on Yahoo)Monangai may have been the only bright spot for a Bears offense that struggled from start to finish in a rain-impacted 9-3 loss to the Vikings. The second-year pro gained 47 yards on 10 carries and added two catches for 11 yards. Meanwhile, starter D’Andre Swift needed 16 carries to gain 45 years, although he was more productive in the passing game (5-54).For the second straight week, Monangai not only averaged more yards per carry than Swift but also passed the eye test, looking explosive, decisive and powerful. Swift is much better in the passing game and therefore will have a higher snap share. But Monangai is quickly building a case to get a larger share of early-down and red-zone opportunities. He’s already a viable flex option.TreVeyon Henderson, Patriots (93%)After sitting out Week 1, Henderson needed just a few minutes of action in his 2026 debut to reward those who bucked the Rhamondre Stevenson hype train and instead grabbed Henderson on draft day. Stevenson, who has never been known as a sure-handed ball carrier, fumbled on the Patriots initial possession, which opened the door for Henderson to make his mark on the second drive. The Ohio State alum quickly ripped off a 39-yard touchdown run, and by the end of the game he had earned 16 carries to Stevenson’s six.Week 2 wasn’t all bad for Stevenson, who averaged 7.2 yards per carry. But Henderson, who finished with 76 rushing yards, reminded everyone that he has a level of explosiveness that Stevenson lacks. The situation in New England is similar to that in Chicago, where the veteran (Stevenson) will play on most passing downs but the carries could be an even split or even slant to the younger player (Henderson). And Stevenson could be one more fumble away from a role reduction.Blake Corum, Rams (87%)For the second straight week, Corum and Kyren Williams had nearly the same number of touches, with both players logging 12 carries and Williams topping Corum by just one reception in an easy Week 2 win over the Giants. The snap share tells a different story, as Corum was below 30% and Williams was over 60% for the second straight week.While Williams remains the lead back for the Rams, Corum is used heavily while he is in the game. The third-year pro is averaging 6.0 yards per carry and will collect a handful of touchdowns. Corum’s lack of usage in the passing game (16 career catches) limits his value to a low-end flex option until we reach bye weeks.Rachaad White, Commanders (56%)After White was a non-factor in Week 1, he was arguably Washington’s
