The Lions have had no answer for Justin Fields' rushing over the past two seasons, so if you've got him on your roster in Week 14 and you're facing a must-win game, you're in luck.

Fields had 23.2 Fantasy points against the Lions just three weeks ago, thanks in large part to an aggressive game plan that saw him run 18 times for 104 yards. That matched Fields' career high in carries, and it's not hard to see how the Bears came up with that game plan; the Lions have struggled to contain Fields on the ground. He rushed for 279 yards in two games against them last season, too. 

You can bet they're putting in extra work to try to figure out how to slow Fields down this week, but the thing is, if they commit more defenders to that cause, they run the risk of getting burned by Fields and D.J. Moore, which has been one of the more lethal QB-WR combinations in the league this season. There are still a lot of questions in Chicago about whether they've got their long-term answer at QB, but we're seeing more and more glimpses this season of how hard it can be to slow Fields down when he can make plays in both facets of the game. 

Fields is Jamey Eisenberg's Start of the Week for this matchup, and in the rest of this evening's newsletter, we've got the rest of Jamey's Start 'Em & Sit 'Em calls for you. That means his top plays and biggest fades at each position, plus sleepers, bust alerts, and more. Tomorrow morning, my preview of every game on the Week 14 schedule, including all of the latest injuries you need to know about before the first lineup lock of the week will be in your inbox, so keep an eye out for that. 

For now, here are Jamey's top starts and sits: 

• Week 14 Position Previews: QB | RB |  WR |  TE
• Jamey, Dave, Heath's Rankings
• My Week 14 Rankings:  QB |  RB | WR | TE
  

Start 'Em: Brock Purdy and Jordan Love

"Purdy is making a strong case for NFL MVP with his play of late for the surging 49ers . He's scored at least 29.8 Fantasy points in three of his past four games and has at least 296 passing yards in four of his past five outings. His worst outing over that stretch was Week 12 at Seattle when he passed for just 209 yards, one touchdown and one interception and only scored 12.5 Fantasy points. But he'll do much better in the rematch with the Seahawks this week. Purdy has never scored fewer than 20 Fantasy points in all eight home games he's started in San Francisco going back to last season."

Sit 'Em: Jared Goff and Matthew Stafford

"Goff is more of a bust alert than a must-sit option since he's scored at least 20.3 Fantasy points in three of his past four games. The one game where he failed to top 20 Fantasy points was Week 11 against Chicago, who held him to 17.7 points with three interceptions. The Bears now have seven interceptions in their past two games and have kept three quarterbacks in a row (Bryce Young, Goff and Joshua Dobbs) to fewer than 18 Fantasy points. Goff has also scored 16 Fantasy points or fewer in three of four outdoor games this season."

Start 'Em: Zack Moss and James Cook

"Moss had a bad game at Tennessee in Week 13 in his first outing back in the lead role without Jonathan Taylor (thumb). Moss had 21 total touches (two catches on three targets), but he managed just 57 total yards. He should rebound this week against the Bengals , who have allowed a running back to score at least 15.9 PPR points in four games in a row and in six of the past seven contests, including eight touchdowns over that span. I like Moss as a top-10 running back in all leagues."

Sit 'Em: Najee Harris and Zach Charbonnet

"Harris was a huge letdown as the Start of the Week in Week 13 when he scored just 9.7 PPR points at home against the Cardinals. It's clear he needs to score a touchdown with only three games over 70 rushing yards on the season and a combined three catches on five targets in his past three outings. He's also still losing touches to Jaylen Warren, and the Steelers are starting Mitch Trubisky this week in place of Kenny Pickett (ankle). New England has also shut down Saquon Barkley and Austin Ekeler the past two games, holding them to a combined 10.9 PPR points. If the Patriots keep Harris out of the end zone, then his production will also be minimal in Week 14."

Start 'Em: Rashee Rice and Courtland Sutton

"Rice has finally become the receiver we hoped for in the past two games against the Raiders and Packers. Over that span, he has 19 targets for 16 catches, 171 yards and a touchdown, and he scored at least 14.4 PPR points in each outing. He should be considered a No. 2 Fantasy receiver in the majority of leagues against the Bills in a potential shootout, and Patrick Mahomes will continue to lean on Rice in this matchup. It helps that Buffalo has allowed 12 receivers to score at least 14.2 PPR points this season."

Sit 'Em: Calvin Ridley and Diontae Johnson

"We're not expecting Trevor Lawrence (ankle) to play in Week 14 at Cleveland, and Christian Kirk (groin) is also out. That puts a big target on Ridley's back, and the Browns are expected to have cornerback Denzel Ward (shoulder) back in action. Even if Lawrence somehow plays, I'd still be down on Ridley given the matchup since Cleveland is No. 2 in fewest Fantasy points allowed to opposing receivers. I would only start Ridley in three-receiver leagues for Week 14."

Start 'Em: Taysom Hill

"Hill was a Fantasy star once again in Week 13 against Detroit with 13 carries for 59 yards and a touchdown, and he caught two passes for 15 yards on two targets. He should do damage against the Panthers in Week 14 on the ground since Carolina has one of the worst run defenses in the NFL, and Hill should also see time under center with Derek Carr (concussion) not expected to play. Hill has the chance to be a top-five tight end in all leagues."

Sit 'Em: Kyle Pitts

"Pitts already faced Tampa Bay in Week 7 and finished that game with three catches for 47 yards on five targets. He comes into Week 14 in the rematch having scored 6.5 PPR points or less in three of his past five outings, and he only has one touchdown this season. There's no reason to trust Pitts in the majority of leagues in Week 14."

Start 'Em: Browns vs. JAX

"The Browns will likely be facing C.J. Beathard at quarterback with Trevor Lawrence (ankle) hurt, and Christian Kirk (groin) is also out. Denzel Ward (shoulder) is also back in the secondary for Cleveland, and the Browns DST should be fantastic in Week 14. It's been tough to trust the Browns defense lately since they have a combined four sacks and one turnover against Pittsburgh, Denver and the Rams , but this is a big bounceback spot against the depleted Jaguars."

Sit 'Em: Cowboys vs. PHI

"In the first game against the Eagles in Week 9, the Cowboys allowed 28 points with no turnovers and just three sacks. We know the Cowboys DST has been an MVP for a lot of Fantasy managers, but this is a good week to avoid this unit. Dallas also struggled defensively against Seattle in Week 13 at home with 35 points allowed, one sack and one interception, and the Eagles offense should do damage in this expected high-scoring affair."
