Start 'Em & Sit 'Em is the ultimate weekly look at NFL matchups and how they'll affect your fantasy football team. Fantasy superstars such as Patrick Mahomes and Christian McCaffrey will not be featured in this column. All player matchups are based on a PPR scoring system. For your final starting lineup decisions, check my weekly fantasy football lineup rankings.
Start of the Week
Garoppolo was an absolute stud in last week's win over the Saints, and he'll be a starter in countless fantasy leagues when the Niners host the Falcons in Week 15. Atlanta's defense that allowed a total of 24 touchdown passes and the third-most fantasy points to opposing field generals, so Jimmy G should put up another solid stat line.
Winston is coming off a monster performance, scoring nearly 35 fantasy points against the Colts. Assuming he isn't hindered due to a tiny fracture in his hand, Winston is a virtual must start when the Bucs face the Lions in Detroit. Their defense has allowed an average of more than 20 fantasy points per game to quarterbacks in 2019.
Tannehill continues to play at a league-winning level, as he's now put up at least 18.9 fantasy points in all but one of his seven starts for the Titans. He's in a good spot to succeed once again, as the Texans have given up 20-plus fantasy points to quarterbacks in two straight weeks, including rookie Drew Lock's nearly 24-point game just a week ago. Keep Tannehill in your starting lineups this weekend.
Mayfield is not a lock to produce huge totals by any stretch, but he does have one heck of a good matchup in Arizona. Over the last four weeks, their defense has allowed the most passing yards per game and the fifth-most fantasy points to enemy quarterbacks. That bodes well for Baker in what could turn into a real shootout in the desert.
Goff hasn't been a reliable fantasy option all season, but he is a viable super flex or two-quarterback leaguer against the Cowboys. Their defense has been hammered by enemy signal-callers in recent weeks, as Jeff Driskel, Josh Allen and Mitchell Trubisky have all had big games against them. That makes Goff worth a roll of the dice.
Sit of the Week
Trubisky has been on fire lately, but his success has come in two games against the Lions, a game against the Giants and another versus a Cowboys team that seems to have quit. Next up are the Packers, who have allowed just nine touchdown passes and an average of 12.6 fantasy points to quarterbacks at Lambeau Field.
Cousins has been one of the better fantasy quarterbacks in the second half of the season, but he has failed to score 18 points in each of his last two games. He has a tough matchup in Week 15 in Los Angeles, as the Chargers have allowed 18 touchdown passes and the sixth-fewest fantasy points to enemy quarterbacks this season.
I am a huge fantasy fan of Allen, but we saw last week what can happen when he faces a really good defense. He has the same issue in Week 15, as the Steelers have allowed a mere 11.5 fantasy points per game to opposing quarterbacks at Heinz Field. In fact, Pittsburgh is the lone team to keep Lamar Jackson out of the top 15 in 2019.
Brissett is coming off a strong fantasy performance in Tampa Bay, posting nearly 23 fantasy points. Still, a road matchup in New Orleans on Monday night doesn't bode well for a repeat performance. With T.Y Hilton and others injured, Brissett could struggle against a Saints defense that can be tough on quarterbacks on their home field.
Lock has been pretty impressive in his first two NFL starts, including a 23-point game in last week's win over the Texans. However, I wouldn't chase the points in super flex leagues. Lock will play in Arrowhead Stadium this week, which is one of the loudest venues in the NFL. The Chiefs defense has played very well lately too, so I'd fade Lock.
