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: Colin Kaepernick, QB
Colin Kaepernick threw for three touchdowns last week, and he now gets his favorite receiver Michael Crabtree back. Also helps that the 49ers play the St. Louis Rams in Week 13 whose pass defense has struggled recently -- gave up 352 passing yards to backup Chicago Bears quarterback Josh McCown last week. Put your early-season resentment towards Kaep aside and start him.
Raider to start: Rashad Jennings, RB
Last week the Dallas Cowboys gave up 202 yards rushing to NY Giants' running backs. The week before? 244 rushing yards to the New Orleans Saints. And the week before that? 140 yards rushing to Adrian Peterson. Moral of the story? Start Jennings, who is averaging 103.25 rushing yards a game since taking over for the injured Darren McFadden.
49er to sit: Frank Gore, RB
The last time running back Frank Gore played the St. Louis Rams, he ran for a season-high 153 yards and a touchdown. While the 49ers do play the Rams again in Week 13, Gore has been playing less snaps -- 59 percent last week, as opposed to 75 percent on the season -- as the season wears on. Gore should play well, but not put up the gaudy stats circa Week 4.
Raider to sit: Raiders, D/ST
The Oakland Raiders defense has played well the past five games giving up less than 25 points in four of those contests. Unfortunately, the Raiders rank No. 25 in the NFL in passing yards allowed per game and their Week 13 opponent, the Dallas Cowboys, bode all-world receiver Dez Bryant and the No. 12 ranked passing attack.
NFL trend: Waiver-wire help
RB- Toby Gerhart - Quietly has had 67 and 91 yards rushing the past two weeks. The Vikings play the Henry Melton-less Chicago Bears, who give up a league-worst 145.2 rushing yards a game. Keep an eye on the Stanford alum.
WR- Brandon LaFell - The Carolina Panthers No. 2 wide receiver has seen over seven targets in three of the last four games. Panthers play the Tampa Bay Bucs, whose defense has given up 13 receptions, 211 yards and two touchdowns to opposing No. 2 receivers the past two weeks. Start LaFell.
TE- Ladarius Green - The tight end is slowly making himself fantasy relevant with back-to-back 80 yard receiving games for the Chargers. Stash Green with an eye on future production from him.
Buy-low candidate: C.J. Spiller, RB, Buffalo Bills
After the bye week, Bills running back C.J. Spiller should be 100 percent healthy (ankle). So far in 2013 he hasn’t been productive averaging 60.3 total yards per game. Good news is on the horizon when the Bills play the No. 5 worst run defensive team, the Atlanta Falcons. Over the past three weeks Atlanta’s defense is giving up a 5.95 yard average on 64 carries to starting running backs.
Sell-high candidate: Maurice Jones-Drew, RB, Jacksonville Jaguars
Maurice Jones-Drew has seen a nice revitalization the past three weeks, scoring a touchdown in each contest. But he still looks slow -- 3.02 yard average per carry last three games. The Jaguars play the Cleveland Browns in Week 13 whose defense is No. 6 against the run, giving up 97.7 yards per game on the ground. Not good news for MJD.
Star to sit: Seattle Defense/Special Teams
The Seattle Seahawks have the No. 2 ranked defense in 2013 -- giving up 293.3 total yards, 16.3 points and 180.4 passing yards a game -- but this won’t be the same defense Week 13 against the New Orleans Saints. Starting corner Brandon Browner is out with an injury and No.3 corner Walter Thurmond III is suspended. Stepping into Thurmond and Browner’s corner position is Perrish Cox; he was signed on Tuesday, and will start. Don’t expect much from the Seahawks against the Saints’ No. 3 ranked offense.
No-namer to start: Rod Streater, WR, Oakland Raiders
Receiver Rod Streater has taken off over the past four weeks, going over 80 receiving yards in three of those games. With Denarius Moore (injured shoulder) ruled out for Thursday's game in Dallas, Streater should be the Raiders’ No.1 receiver. The Cowboys are ceding 9.2 targets and 77.1 yards per game to No. 1 receivers. Fantasy owners should be thankful for the former Temple alum’s Thanksgiving day matchup.
