49ers, Vikings Week 12 Fantasy Preview

Jimmy Garoppolo has put any Trey Lance talk to rest (for now) posting an NFL-high four-straight games with a 100+ passer rating, and he's also a fantasy option this week while looking at increased volume. Jimmy G has gotten 9.2 YPA over the last month and is a top-15 fantasy QB against a Vikings defense allowing the sixth-most fantasy points to quarterbacks this season and will be missing defensive linemen Dalvin Tomlinson and Everson Griffen.

Elijah Mitchell remains questionable after finger surgery, and there's a good chance Jeff Wilson Jr. is SF's feature back again Sunday. Wilson Jr. didn't have a big fantasy game but racked up 20 touches last week and gets an easier matchup Sunday; Minnesota has allowed a league-high 4.8 YPC and ranks No. 27 in run defense DVOA. Trey Sermon would likely see action if Mitchell were forced to sit this week, and Wilson Jr. would become a top-15 fantasy RB.

Deebo Samuel actually ranks third in San Francisco's target share (20.5 percent) since George Kittle returned, but he's a top-five fantasy WR anyway given his rushing ability (and SF's extremely narrow target tree); he was a top-20 PPR WR last week despite having just one catch for 15 yards thanks to his rushing. Minnesota and San Francisco like to implement slow-paced offenses, but both QBs could be forced to throw more than usual in a game that should be high scoring.

Brandon Aiyuk can safely be considered a top-25 fantasy WR now back producing as a full-time player and against a Vikings defense allowing the third-most fantasy points to wideouts this season. Aiyuk has responded well after a painfully slow start to 2021. After not seeing one target inside the 10 yard line since Week 4 of 2020, Kittle has seen one in each of the past three games, securing all three for touchdowns. He's a top-three fantasy TE moving forward.

The 49ers defense has a tough test against a good Minnesota offense, as Kirk Cousins has posted a 12:0 TD:INT ratio on the road this season. SF's fantasy D/ST is just an OK start this week, as they've allowed more yards per play at home this year. Cousins is a top-12 QB in this matchup, while Dalvin Cook, Justin Jefferson and Adam Thielen are all must-starts. With the final NFC playoff spots up for grabs, this is a huge game in the conference, with the first tie-breaker being head-to-head.
