In most league formats, Week 14 marks the last week of the regular fantasy football season. Your last chance to add and drop players who will or will not be with your team for the crucial playoff weeks. Perhaps you do not need to add anyone and you have been rolling with the same guys all year. In that case, consider yourself lucky.

Being active on the waiver wire is always one of the biggest keys to building a playoff contender, and that continues to hold true as the fantasy season hits the final stretch.

Here are six waiver wire pickups to target entering Week 14:

RB Raheem Mostert: 14.1% rostered (ESPN)

In what was once a crowded backfield in San Francisco with Matt Breida and Tevin Coleman having a majority of the carries, it was hard to judge which 49ers running back would be worth adding. Mostert has survived the injury bug that has started to attack this 49ers offense and has taken over as the lead back.

Against Baltimore in Week 13, Mostert totaled 19 carries for 146 yards and a touchdown in a downpour that lasted all game. Mostert brings a dynamic speed and toughness aspect to this young 49ers team.

The upcoming schedule isn’t great, but Mostert has flex appeal—especially if something happens to Coleman and/or Breida.
