Who Should I Start? Christian McCaffrey or Kyren Williams

Updating a previous report, the San Francisco 49ers may place running back Christian McCaffrey (Achilles, calf) on the Injured Reserve on Saturday, which would rule him out for at least the next four games. The Niners ruled McCaffrey out for Week 2 versus the Minnesota Vikings this Sunday after he was unable to practice on Friday. CMC suffered a calf strain early in training camp, but he's also dealing with Achilles tendinitis, which is why he sat out the season-opening win over the New York Jets on Monday night. This is pretty much a worst-case scenario for fantasy managers that took McCaffrey at the top of their drafts, as he's now likely to miss at least the first month of the season. CMC obviously needs to be stashed everywhere. Jordan Mason, who went off as the team's RB1 in Week 1 in place of McCaffrey, now sees his fantasy stock rise even more. He's rostered in 82% of Yahoo leagues right now.

Los Angeles Rams running back Kyren Williams found the end zone in Week 1 at the Lions against Detroit's very stout run defense. The touchdown salvaged an otherwise subpar night for the talented running back. Williams rushed 18 times for 50 yards (2.8 yards per carry) and caught three passes for four yards. The Notre Dame product is a very versatile back and the good thing for his fantasy managers is he saw a massive snap share in the backfield compared to Ronnie Rivers and rookie Blake Corum. The Cardinals were gashed on the ground by the Bills in Week 1, making Williams a strong play in Week 2 in the Rams' game at Arizona. Look for Williams to find pay dirt and remain involved in the passing game as well. His upside is extremely high in this matchup and his volume makes his floor pretty high as well.
