Editor's note: Welcome to the weekly installment of "Tacklin' Fantasy," our recap of the news and trends you need to keep top of mind for fantasy dominance
49er to start: Vernon Davis, TE
The last time the Seattle Seahawks nearly lost was Week 9 against the Tampa Bay Buccaneers. What did the Bucs do? They threw to their tight ends for a combined five receptions, 60 yards and two touchdowns. The blueprint is there for the 49ers, expect Vernon Davis, who himself has scored a touchdown in three straight games, to have play well this Sunday.
Raider to start: Defense/Special Teams
Two words: Geno Smith. The Raiders opposing quarterback in Week 13 hasn’t thrown for a touchdown since before the World Series started, a span of five games. He also leads the NFL in interceptions with 19, while adding eight fumbles. The Raiders defense has had multiple sacks in each of the past four games.
49er to sit: Anquan Boldin, WR
In Week 2, against the Seahawks, Anquan Boldin had just one reception for seven yards. The 49ers play the Seahawks again in Week 13 and expect much of the same from Boldin against the physical corners. Michael Crabtree and Vernon Davis should poach some targets from the 11-year veteran.
Raider to sit: Rashad Jennings, RB
Running back Rashad Jennings has had a nice fantasy run over the past five games, but his stats against the Cowboys last week were misleading as his two rushing touchdowns overshadowing his paltry 2.1 yards-per-carry average. The matchup looks bleak this week against the New York Jets' stout front seven that hasn’t given up a 75-yard rusher all season.
NFL trend: Waiver-wire help
QB: Josh McCown -- McCown has come up big the past two games with a combined 707 passing yards. Chicago’s quarterback bears another great matchup against the No. 31 ranked pass defense – the Dallas Cowboys. Slot Jay Cutler in if he’s cleared and starting for McCown otherwise start the Sam Houston State alum.
WR: Ace Sanders -- The Jaguars wide receiver had four receptions for 61 yards two weeks ago against the Texans. The crafty but diminutive receiver has seen 10 or more targets in two of the past three weeks.
TE: Anthony Fasano -- The Chiefs tight end has scored in three straight games. If he's cleared from a concussion, he'll face a Redskins team that has given up 60-plus receiving yards and a touchdown to tight ends in each of the past two weeks.
Buy-low candidate: Eddie Lacy, RB, Green Bay Packers
Although the Packers running back ranks No. 9 in the NFL in rushing yards with 822, he has come across some difficult games recently -- especially since starting quarterback Aaron Rodgers broke his collarbone. The rookie out of Alabama has been held below 30 rushing yards in two of the past three games, but that should change this week against the Atlanta Falcons. In three of the previous four weeks, the Falcons malignant run defense has awarded starting running backs with at least 140 yards; no-brainer, start Lacy.
Sell-high candidate: Andrew Luck, QB, Indianapolis Colts
Quarterback Andrew Luck’s Indianapolis Colts offense has been lacking an identity since Reggie Wayne’s injury in Week 7. Darrius Heyward-Bey was asked to step up in Wayne’s absence, and he’s falling short, averaging a mere 1.8 catches per game since the injury. With Luck’s lack of a receiving corps outside -- T.Y. Hilton and Coby Fleener -- and the inability for the Colts to run -- 109.4 yards per game -- Luck is left in no-man’s land in fantasy against the No. 8 ranked pass defense this week, the Cincinnati Bengals.
Star to sit: Tony Gonzalez, TE, Atlanta Falcons
Future hall-of-fame tight end Tony Gonzalez has had a typical Tony Gonzalez season in 2013 -- second on the team in receptions and yards while leading the Falcons in touchdowns with five. But receiver Roddy White is finally healthy and cutting into Gonzalez’s production (42 yards last week to White’s 143). The former Cal standout’s matchup isn’t good this week against the Green Bay Packers, a team that has held opposing tight ends under 37 yards in each of the past five weeks.
Star to sit 2.0: Josh Gordon, WR, Cleveland Browns
This one has a caveat. Gordon -- even after his 498 receiving yards over the past two games -- is only the star to sit if the Cleveland Browns have to go with one of the two quarterbacks they signed in the past two weeks -- Caleb Hanie or Alex Tanney. Both quarterbacks lack arm strength and the Browns play the New England Patriot, who boast physical corner Aqib Talib. Do you really think a head coach like Bill Belichick wouldn't scheme against Gordon to derail him from his recent torrid play?
No-namer to start: Tiquan Underwood, WR, Tampa Bay Buccaneers
Two weeks ago Buccaneers receiver Tiquan Underwood had a breakout game with three receptions for 108 yards and two touchdowns. Why? The Bucs’ opponent, the Detroit Lions, shifted coverage to attempt to limit Tampa Bay’s No. 1 receiver Vincent Jackson. Look for the same trend this week when the Bucs play the Buffalo Bills. The Bills are giving up an average of 7.7 targets to No. 2 receivers, and Underwood can break one at any time with his 4.31 40-yard speed.
