If you're asking the question, "Should I Start Jamaal Williams in Fantasy Football in Week 11 2017?", you've come to the right place. We've got a few reasons why Williams is indeed start-worthy for your fantasy football matchup with week. In addition, Kevin Kinder already listed some reasons why he's a solid DFS play for Week 11.
The (perhaps unsurprising) answer is that you should be starting the Packers running back in most formats today. Unless your roster is stacked beyond reason, he's likely to be your best flex option. And, well, if you were high enough on waiver priority to claim Williams, your roster probably isn't that stacked. If you're in a FAAB league, someone who was really desperate for a running back was probably willing to bid more.
The point is, Williams is a fairly obvious must-start. With Ty Montgomery and Aaron Jones out for the week, he's likely to get a significant number of touches. Volume is one of the best things you can hope for from a running back. Last week, he got 20 carries for 67 yards, and added 7 yards on one catch.
74 total yards and no score would make for a fairly paltry fantasy performance. But Williams is likely to have a better performance against a Ravens defense that's allowing 4.2 yards per carry to opposing running backs this season. Furthermore, he could get even more touches considering he'll be the Packers' best running option for the entire game instead of taking over partway through the game like he did last week.
This is the same Ravens defense that saw Jordan Howard put up 167 total yards against them in Week 6. While it would be unreasonable to expect Williams to do the same, he's a clear RB2 this week. If you have him on your roster, make sure he's in your lineup.
