Although firing head coaches mid-week ahead of a game is uncommon, a change occurred in Jacksonville, where Urban Meyer was dismissed after a 2-11 start. Jaguars fans will hope the move will lead to a resurrection of running back James Robinson's workload, after he was persona non grata in Meyer's offense. The Jaguars play the fourth-worst defense against opposing running backs in the NFL in Week 15 when they host the Houston Texans. How high should Robinson be in your Fantasy football rankings?

Robinson only received five carries in the season-opener at Houston this year, but since their bye in Week 10, the Texans have allowed 691 rushing yards in four games. Jacksonville's offensive line is beat up, but the perception of Robinson no longer being held up by Meyer could move him up the Fantasy football RB rankings. Before locking in any Week 15 Fantasy football picks, be sure to check out the Week 15 Fantasy football predictions from the proven computer model at SportsLine.

When it comes to ranking players, SportsLine's model beat human experts in Fantasy football for the past several seasons especially when there were big differences in ranking. 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 was extremely high on Saints quarterback Taysom Hill, ranking him as a top-10 player at his position. The result: Hill rushed for 73 yards and two touchdowns while also throwing for 175 yards. Anybody who had him in their lineup was well on their way to a huge week.

Now, the model, which simulates every NFL game 10,000 times, has revealed its Fantasy football rankings for Week 15 of the 2021 NFL season. Head to SportsLine now to see them.

Top Week 15 Fantasy football picks 

One player the model is high on this week: Broncos running back Javonte Williams. Two weeks ago, with Melvin Gordon out with injury, Williams ran for 102 yards and added 76 more through the air with a touchdown against the Chiefs. Last week against the Lions, with Gordon back in action, he still finished with 73 yards rushing and two total touchdowns.

The Broncos offense has been led by its running backs, with quarterback Teddy Bridgewater not moving the needle in a significant way. The Broncos play the Bengals this week, who started the week with two defensive front-seven starters unable to practice. Cincinnati has also allowed opposing running backs to catch 92 passes this season, third most in the NFL. Even with Gordon continuing to share work in the backfield, SportsLine's model says Williams will have a more productive week than starters like Ezekiel Elliott, Antonio Gibson and Devonta Freeman.

And a massive shocker: Seahawks quarterback Russell Wilson, who's thrown for at least 230 yards and two touchdowns in each of his last three games, stumbles big-time and doesn't even crack the top 20 at his position. Wilson has turned it on in recent games, but he has an extremely tough matchup this week against the Los Angeles Rams. 

In his last start against the Rams, Wilson finished with just 158 passing yards, one touchdown and one interception. Plus, the Seahawks have failed to score more than 20 points against Los Angeles in their last five meetings against their NFC West rivals. With such a tough matchup on Sunday, Wilson is a player to consider putting on the bench in Week 15.

The model is also calling for an under-the-radar quarterback 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. You can only see who it is here.
