It's a pivotal week in Fantasy football, with most leagues wrapping up their regular seasons. With playoff berths and seeding on the line, there's a lot at stake when evaluating the latest Week 13 Fantasy football rankings. Setting your lineup is even tougher this week, with several high-scoring players unavailable. Jaguars running Leonard Fournette is suspended this week for doing his best Fury vs. Wilder impersonation last Sunday, ex-Chiefs tailback Kareem Hunt was released on Friday, and Melvin Gordon is out with an MCL injury for the Chargers on Sunday Night Football. Add in concerns over how effective wide receivers A.J. Green and Stefon Diggs will be and start-sit decisions become even harder. That's why you'll need to check out the proven Week 13 Fantasy football rankings from the advanced computer model at SportsLine.

When it comes to ranking players, their advanced computer model beat human experts in Fantasy football last season when there were big differences in ranking. And the model was closest to the hole overall, meaning it best pinpointed where every player would finish each week. Over the course of a season, that could literally be the difference between winning your league or going home empty-handed.

Last week, the model advised owners to bench Panthers tight end Greg Olsen, saying he'd finish well outside the top 10 tight ends. The result: Olsen had just two receptions for 11 yards. Anyone who benched him dodged a major bullet. 

Now the model, which simulates every game 10,000 times, has revealed its Week 13 Fantasy football rankings. One player the model loves this week: Buccaneers tight end Cameron Brate. 

Tampa Bay placed starting tight end O.J. Howard on injured reserve prior to last week's game against the 49ers and Brate responded with his first touchdown in five weeks. Now, his value in the Buccaneers' passing game could be further enhanced by news that wide receiver DeSean Jackson won't play on Sunday against the Panthers. 

Against a Carolina defense that has given up a whopping nine touchdowns to tight ends this season, Brate is among SportsLine's top options at the position in Week 13 and is projected to outscore tight ends like Jimmy Graham, Jordan Reed and Trey Burton. If you're looking for a fill-in, Brate provides plenty of value and is still available in 25 percent of CBS Sports leagues.

And a massive shocker: Chargers quarterback Philip Rivers stumbles big-time this week against the Steelers and finishes outside the top 15. He's a player to bench in Week 13. 

Rivers is coming off a historic performance against the Cardinals, completing 28 of 29 passes for 259 yards and three touchdowns. Rivers' 96.6 percent completion rate set a single-game record for quarterbacks who have attempted at least 20 passes, but SportsLine's model says he'll struggle big-time against the Steelers, who have held opposing quarterbacks to under 200 yards passing in four of their last five games.

The model is also calling for a surprising running back you aren't even thinking about to finish in the top 10 of its Fantasy football rankings. This pick could be the difference between winning big and going home with nothing.

So who should you sit and start this week? Visit SportsLine now to get Week 13 Fantasy football rankings for every position, plus see which running back is going to come out of nowhere to crack the top 10, all from the model that out-performed experts big time last season.
