What a difference a week – and a coaching change – makes. 

The Steelers offense was one of the biggest laughing stocks in the NFL under Matt Canada, and Najee Harris might have been the butt of more jokes than anyone. Now? He's Jamey Eisenberg's Start of the Week for Week 13!

The Steelers offense just looked a lot more functional last week, the first since Canada's ouster, and Harris obviously benefited, with 15 carries for 99 yards and a touchdown. And now he gets to take on a Cardinals offense that has been miserable against the run, allowing at least 100 yards in 10 of 12 games to date – and 90-plus in the other two! Harris figures to get at least 15 carries against them, and given the way this season has gone for the Cardinals, that might mean 100 yards and another touchdown.

I'd rather have Harris' backfield mate, Jaylen Warren, who figures to get 12-15 carries of his own and has the passing game role as well, but I think both are well worth starting this week – they're both in my top-24 at RB, and they're both top-24 options for Jamey Eisenberg, Dave Richard, and Heath Cumming, too. 

In the rest of this evening's newsletter, we've got the rest of Jamey's Start 'Em & Sit 'Em calls for you, with his top plays and biggest fades at each position. Tomorrow morning, my preview of every game on the Week 13 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 13 Position Previews: QB | RB |  WR |  TE
• Jamey, Dave, Heath's Rankings
• My Week 13 Rankings:  QB |  RB | WR | TE
  

Start 'Em: Brock Purdy and C.J. Stroud

"Purdy had a bad Fantasy outing in Week 12 at Seattle with 12.5 points, which snapped a three-game streak of him scoring at least 20 points. While he's struggled on the road this season -- he has four games with fewer than 15 Fantasy points in six games outside of San Francisco -- I still like him in this spot. The Eagles are No. 2 in most Fantasy points allowed to opposing quarterbacks, and four quarterbacks in a row have scored at least 20.9 points. Philadelphia's defense just played 95 snaps in Week 12 against Buffalo, which is the most of any team this season, so the Eagles should be tired. That's a huge advantage to Purdy and all the 49ers, who last played on Thanksgiving against the Seahawks."

Sit 'Em: Kyler Murray and Baker Mayfield

"Murray has performed well in his comeback from last year's torn ACL with at least 22.4 Fantasy points in two of three games this season. He's rushed for a touchdown in each outing, and he has two contests with at least 33 rushing yards. He's more of a bust alert than a sit in Week 13, but I don't love this matchup for him at Pittsburgh. The Steelers have only allowed one quarterback to score more than 16.7 Fantasy points since Week 4, including matchups with Lamar Jackson and Trevor Lawrence, and Pittsburgh's pass rush should be a problem for Murray. I would only start him in Superflex and two-quarterback leagues in Week 13."

Start 'Em: Rhamondre Stevenson and Zack Moss

"After a sluggish start, Stevenson has turned his season around, and he comes into Week 13 having scored at least 13.2 PPR points in five of his past six games. He has over 100 total yards in three games in a row, with two touchdowns over that span, and he's back involved in the passing game with at least four catches in four of his past six outings. The Chargers are No. 8 in most Fantasy points allowed to opposing running backs, and nine running backs have scored at least 13 PPR points against Los Angeles this year. Stevenson is a borderline No. 1 running back in all leagues for Week 13."

Sit 'Em: A.J. Dillon and Brian Robinson

"We'll see if Dillon starts again for Aaron Jones (knee) in Week 13 against Kansas City, and Dillon would be a flex option at best in that matchup. He did OK in Week 12 at Detroit with 11.1 PPR points, and he handled 17 total touches, including three catches for 38 yards on three targets. But this is a tough matchup against the Chiefs , who have not allowed a running back to score more than 9.9 PPR points against them this season without a touchdown. And that's a problem for Dillon since he only has one touchdown on the year. Keep an eye on what happens with Jones, and if he's out then Dillon could be a flex in deeper leagues, just with a limited ceiling."

Start 'Em: Nico Collins and Calvin Ridley

"Collins has been overshadowed by Tank Dell of late, but Collins still continues to produce at a high level. And both Texans receivers should be started in all leagues in Week 13 against Denver. Collins has scored at least 13.5 PPR points in three games in a row, and he has two touchdowns over that span. He also has 20 targets in his past two outings against Arizona and Jacksonville for 14 catches, and I'm expecting this Texans-Broncos game to be a shootout, which favors the passing game in Houston."

Sit 'Em: Christian Watson and Tyler Lockett

"It was great to see Watson play well on Thanksgiving at Detroit with season highs in catches (five) and yards (94) on seven targets, and he scored a touchdown for the second game in a row. Hopefully he's getting hot at the right time. But this is still a crowded receiving corps, and I like Jayden Reed better than Watson, with Romeo Doubs right behind both. For this week, Reed is a No. 3 Fantasy receiver, and Watson and Doubs are borderline starters most in three-receiver leagues. The Chiefs secondary has been amazing this season, especially against No. 1 receivers, and Watson should struggle if he's matched up with cornerback L'Jarius Sneed in this game."

Start 'Em: Trey McBride

"In three games with Kyler Murray, McBride has 25 targets and two outings with at least 13 PPR points. He's the best option in the passing game for the Cardinals, and I'm still starting him even in a tough matchup with the Steelers in Week 13. Pittsburgh is No. 8 in fewest Fantasy points allowed to opposing tight ends, but David Njoku, Dalton Schultz, Mark Andrews and Evan Engram have all scored at least 12.5 PPR points against the Steelers. McBride should follow suit, and he has top-five upside in all leagues for Week 13."

Sit 'Em: Gerald Everett

"One of my favorite stats this week is that the Chargers have had a tight end score at least 10.8 PPR points in five of the past seven games, with Everett hitting that mark three times over that span, including Week 12 against Baltimore when he caught four passes for 43 yards and a touchdown on four targets. That said, he doesn't have an easy matchup in Week 13 at New England since the Patriots are No. 5 in fewest Fantasy points allowed to tight ends. I don't mind Everett as a low-end starter in deeper leagues if you're desperate, but New England has only allowed one touchdown to a tight end and just three guys to top 7.6 PPR points this year."

Start 'Em: Jaguars vs. CIN

"In the first game for Jake Browning in place of Joe Burrow (wrist) in Week 12 against Pittsburgh, the Bengals offense managed just 10 points. Browning was sacked four times with an interception, and Cincinnati had only 252 yards of total offense. The Jaguars haven't had an interception in three games in a row and only have two fumble recoveries over that span, but Jacksonville had four sacks against C.J. Stroud in Week 12 and should make things uncomfortable for Browning and the Bengals in Week 13. I like the Jaguars DST as a No. 1 Fantasy option in all formats."

Sit 'Em: Eagles vs. SF

"Philadelphia's defense played a whopping 95 plays in Week 12 against Buffalo, and this should be a tired unit coming into Week 13 against San Francisco. Meanwhile, the 49ers should be well rested after last playing on Thanksgiving. The Eagles have allowed at least 31 points in two of their past four games, and Philadelphia only has two sacks in the past two games against the Chiefs and Bills. The 49ers also have just one turnover in their past three games but have scored at least 27 points in each outing over that span."
