Deebo Samuel or Jauan Jennings Week 15 Start 'Em, Sit 'Em: Fantasy football projections for WRs 

The San Francisco 49ers and Los Angeles Rams will kick off Week 15's slate of games as we approach the business end of the season. Week 15 also means we are officially in fantasy playoff season, which means added pressure to make the right calls in your lineups.

Given the fact that this Niners offense has not exactly looked consistent in terms of fantasy output between Deebo Samuel, Brandon Aiyuk, Christian McCaffrey, Jauan Jennings and Brock Purdy, here's everything you need to know about the Niners receiving room before making any lineup decisions for tonight.

Deebo Samuel's fantasy projection for Week 15

When Christian McCaffrey was ruled out for the rest of the season with a posterior cruciate ligament injury, the belief was that Deebo Samuel's stock would be on the up given how much the Niners would have to rely on him.

That belief came undone in Week 14. Samuel didn't get more targets than usual but he did see more carries, which doesn't exactly help his fantasy outlook. Given backup running back Isaac Guerendo is likely to miss the TNF showdown tonight, Samuel could well see more rushing volume, tanking his stock.

Samuel is still averaging about six targets a game but it's difficult to rely on him when Purdy has seen more success throwing to George Kittle and Jauan Jennings.

Jauan Jennings' fantasy projection for Week 15

Deebo Samuel's stock has fallen off a cliff but the exact opposite stands true for Jauan Jennings.

Against the Chicago Bears, Jennings caught seven of his eight targets for 90 yards and two touchdowns in what was a crucial win for the Niners' slim playoff hopes.

Brock Purdy appears to trust Jennings in key situations, particularly targeting him on third downs. That bodes well for Jennings' fantasy outlook for the rest of the year. The matchup against this Rams defense is also a pretty favorable one for all of the Niners' receivers.

Like the Browns, the Rams have struggled to contain receivers this year, something that GM Les Snead will have to rectify this summer. All things considered, Jennings figures as a strong WR2 option this week and for the rest of the year.
