Our Week 13 Start ‘Em & Sit ‘Em is an in-depth look at the weekly NFL matchups and how they will impact your lineup decisions for your fantasy football team. Our list of Week 13 running back starts and sits features regular fantasy starters, as well as lesser-known players, who are likely to exceed expectations based on a favorable matchup, or fail to meet expectations due to the strength of their opponent.

Week 13 Start ‘Em, Sit ‘Em: QB | RB | WR | TE

Start ‘Em

Jordan Howard CHI vs. SF

The 49ers run defense will easily win the award for best target for fantasy owners this season. Still allowing a league-worst 171.8 rushing yards per game, you can bet the Bears will be ready to expose that on Sunday when San Francisco comes to town. Howard has been a steady RB2 over the past handful of weeks and will have his best chance to duplicate his monster numbers from Week 8 when he dropped over 200 yards from scrimmage and a TD against the Vikings. Fire him up as an elite RB1 option for Week 13.

Dion Lewis NE vs. STL

While Jeff Fisher may still think Danny Woodhead is the Patriots big threat as a passing-back, it’ll be a combination of Dion Lewis and James White filling that role on Sunday in New England. That being said, with news coming out today that Rob Gronkowski will need back surgery, the Patriots will be forced to dip into their bag of tricks to replace Gronk’s production. All hands on deck should translate into an expedited transition for Lewis back into a large part of the offense. Lewis has looked as shifty as ever, since returning from a knee injury that kept him on the PUP list for the first 10 weeks of the year. While White will still cut into his change-of-pace work, Lewis is the one with the higher ceiling, as he possesses the more dynamic, big-play potential. Lewis has a good chance of receiving close to 15 touches this weekend and look for him to make the most of his workload. He’ll be a solid flex option, especially for those in PPR leagues. Start ’em!

Theo Riddick DET @ NO

After posting pedestrian numbers across his last three games, Theo Riddick is in a prime spot for a bounceback performance in a Week 13 contest in New Orleans. The Saints are allowing the 6th most fantasy points to running backs and also struggle bottling up pass-catching backs. In what projects to be a shootout between Matthew Stafford and Drew Brees, look for Riddick to rip off a few chunk gains, as he has a great chance of finding the end zone in this week’s matchup in NOLA. Start ’em!

Sit ‘Em

Devontae Booker DEN @ JAX

Devontae Booker has been given every opportunity to seize control of Denver’s running game in the wake of C.J. Anderson getting placed on I.R. However, Booker has uninspired during his time as the Broncos’ lead back, averaging just 2.9 rushing yards a game since being handed the keys to the backfield. This week, Booker and the Broncos travel to Jacksonsville to take on a Jaguars defense that is better than their record indicates. In what doesn’t project to be a very high-scoring game, Booker won’t be a very appealing flex option for Week 13.

Rob Kelley WAS @ ARI

After erupting for 137 rushing yards and 3 TDs two weeks ago against the Packers, Rob Kelley was silenced on Thanksgiving, to the tune of 37 yards on 14 carries. This week, Kelley will face a Cardinals defense that is currently allowing the second fewest amount of fantasy points to opposing backs. It’s safe to say, Washington and Kirk Cousins will focus more on moving the ball through the air than on the ground this week in Arizona. It’s not out of the realm of possibility that scatback Chris Thompson could be on the field more, which would cap the number of touches for Kelley. Either way, don’t expect Kelley to pop off for a big week in the desert.

Terrance West BAL vs. MIA

Despite allowing the third most rushing yards in the NFL this season, the Dolphins actually allow the 12th fewest fantasy points to opposing running backs. This has largely been the case of Miami keeping opposing backs out of the end zone, while stiffening up in the red zone. With Terrance West becoming more and more ineffective, the Ravens have gotten Rookie Kenneth Dixon more involved, as he trends towards a larger share of the pie in the Baltimore backfield. This could be the week that Dixon surpasses West in terms of total touches and fantasy owners shouldn’t bank on West being a legitimate RB2 in Week 13. Sit ’em!
