After Christian McCaffrey was traded to the San Francisco 49ers, it was up in the air who would take over running back duties for the Panthers, which was an important detail from a fantasy perspective. It seemed that D'Onta Foreman was the primary runner, but he has been dealing with injuries. Foreman has indicated that the foot and rib injuries aren't going to stop him from being on the field, but it may result in more carries for Chuba Hubbard, even in a great matchup against the Seahawks. Foreman is a good flex option for those that are hesitant to start him as an RB2.
A flex wide receiver is Isaiah McKenzie of the Buffalo Bills. He had a great game in Week 12: six receptions for 96 yards and a touchdown. This could be a fluke and his best game of the year (he followed it up in Week 13 with four receptions for 44 yards), but it also could mean that he is getting more involved in an offense that likes to throw the ball and has Josh Allen at the helm.
