Before setting your Week 15 Fantasy football lineups, you need to see what SportsLine's advanced computer model has to say. When it comes to ranking players, the 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. That could literally be the difference between winning your league or going home empty-handed.

Last week, the model advised owners to bench Bills running back LeSean McCoy, saying he'd finish outside the top 25 running backs. The result: McCoy exited early with a hamstring injury, finishing with just two carries for one yard against the Jets. Anyone who benched him dodged a MAJOR bullet.

Now the model, which simulates every game 10,000 times, has revealed its latest Week 15 Fantasy football rankings.

One player the model loves this week: Vikings receiver Stefon Diggs, who faces a Dolphins defense that gave up over 350 yards and three touchdowns through the air last week. Diggs is projected to be a top-10 wide receiver and outscore players like Michael Thomas, Julio Jones, and Mike Evans.

And a massive shocker: Packers tight end Jimmy Graham stumbles big-time this week against the Bears and doesn't even crack the top 15. He's a player to bench this week.

The model is also calling for a surprising quarterback you aren't even thinking about to finish in the top 10 of the rankings. This pick could be the difference between advancing in the playoffs and going home with nothing.

So who should you sit and start this week? And where does every player stack up?... Join SportsLine right now to get Fantasy football rankings for every single position, and see which shocking QB finishes in the top 10 this week, all from the model that out-performed experts big time last season!
