Video: Ranking All of the Week 9 Fantasy Football Waiver Wire Targets
Kenneth Walker's so good, I don't I don't trust him to have many bad games, right? So, you're dependent on that, dependent on an injury.

Positive signalProjection

Reliable lead back unlikely to have many bad games; handcuff dependent on injury.

High-quality lead back with consistent performance; Kenneth Walker is so reliable that he is unlikely to have many bad games, making him a durable fantasy asset. However, his handcuff value (Emitt Johnson) is dependent on Walker suffering an injury, which is the primary pathway to Johnson's standalone value. If Walker goes down, Johnson could see six targets and 14 carries per week on a great offense.
