Fantasy managers look at the flex spot as a place to put the next best player on their team. Often it is a simple decision, but not always. AJ Dillon, for example, is a great flex option. He's ranked as an RB3, although that may be a bit high. However, for a flex spot, he is someone who had four receptions on four targets in Week 5. He had a receiving touchdown as well. While he's not always getting carries (with Aaron Jones healthy), he is a great PPR flex option.
Another flex option is Rondale Moore. He had a breakout game in Week 2 with more than 100 yards and a touchdown. However, he hasn't been able to match that since. One of these weeks, though, he is going to have another game. Kyler Murray has had a tough couple of weeks, but he's bound to bounce back as well. When he does, be sure to have Moore in your lineup.
