With only two teams on bye in Week 4 and again in Week 5, fantasy football owners should still have plenty of players to fill out their lineups. However, the flex position is often the toughest to fill. Often, this position should be looked at as the next best guy on your roster. Fill your WR, RB and TE slots and then see what guys are left. Some teams are loaded at wide receiver - put a WR in the flex spot. Other teams have a lot of running backs - put one of those in the flex. If you have two solid tight ends, that's a possibility as well.
Sometimes guys like Darrel Williams are good flex options. He's the No. 23 running back this week, but is No. 42 on the flex chart. It's certainly possible that a fantasy owner has two players ahead of him on the running back rankings, so why not start him as a flex? He had two touchdowns in Week 4, and while that may not continue, as long as Damien Williams is out, he'll have value. The San Francisco running backs also are interesting flex candidates, depending on Tevin Coleman's status. But the 49ers play on Monday night so that could complicate matters.
