The most important weeks in Fantasy Football are upon us. Some of you are already in the midst of a playoff matchup, while others still fight for one of the last playoff spots available in their respective leagues. Either way, you'll need to make some tough lineup decisions.

There are plenty of tough decisions at the running back position in Week 14, including a couple of normal reliable starters.

3. Alvin Kamara, New Orleans Saints

I know. You're going to have Kamara in your lineup come Sunday. Just heavily temper expectations for the Saints star. He hasn't reached the end zone since Week 3, and never receives the carries necessary to put up great yardage.

Even Kamara's receiving has seemingly dropped off, as he's had more than 50 yards receiving only twice this year. Up against the aforementioned Niners, his prospects look grim. San Francisco is another elite rushing defense, and with no volume comes little success.

2. Tevin Coleman, San Francisco 49ers

Those who started Coleman last week know what I'm talking about. The Niners' run game is seemingly impossible to predict. Coleman will be the featured back in some weeks, like when San Francisco played the Carolina Panthers. Coleman scored four touchdowns that day. And then there are games when Coleman is placed on the bench as 49ers coach Kyle Shanahan decides to ride the hot hand.

Fellow running back Raheem Mostert had that hot hand against the Baltimore Ravens in Week 13, and the Niners promptly benched Coleman in favor of Mostert for the day. San Francisco has a key showdown with the New Orleans Saints and their top-10 run defense on the horizon. Without a steady workload, Coleman becomes a somewhat risky flex play.

1. Sony Michel, New England Patriots

Michel was an easy pick for this column. He hasn't tallied over 10 points in five games and has been kept out of the end zone since Week 7. Michel has always been somewhat touchdown reliant and just hasn't come through in that category recently.

However, that's not my main concern for Michel. Game script has always factored heavily into the fantasy value of Patriots running backs. Unfortunately for Michel, New England faces the Kansas City Chiefs on Sunday. The Pats will probably be behind by a couple of scores at some point if we use their games against the Baltimore Ravens and Houston Texans as a reference point. That means an extremely heavy dosage of pass-catching back James White and a heavy dose of the bench for Michel.
