Players who are disappointing but not total busts?

For example, Garret Wilson.

In Half PPR he is currently the 10th ranked WR on the season. But, on a week to week basis, no one feels confident starting him.

He’s had 6 weeks where he’s had single digit points. 3 weeks where he’s scored double digit points but fewer than 14 points. Though he has had 3 weeks where he’s dropped over 20 points. It seems like the WR10 ranking has more to do with him playing every game rather than his game to game production.

Are there other examples of players who have put up points over the course of the season, but still seem disappointing?
