From the video

last season he averaged over 20 fantasy points per game. He was the RB5 in points per game. And now for three straight seasons he's been a top six running back. However, if we actually go through and we look at his current cost in Underdog Draft specifically, where I've taken a lot of him, he's being drafted as the running back 11.
STACKED’s take
RB5 finisher priced as RB11; receiving upside in bad offense
Averaged 20.4 fantasy points per game last season and finished as RB5 in PPG; been a top-six running back for three straight seasons. Currently being drafted as RB11 in Underdog despite this historical finish rate. While the Miami Dolphins project to be a bottom-four offense (19.1 PPG, down from 20.4 last season), this downside is already priced in at his mid-second-round cost; if the offense were projected to be good, he'd be a top-five pick. Jeremiah Love notes Achane's receiving ability gives him more upside than other RBs in poor offenses, and the Dolphins' new coaching staff and quarterback play create uncertainty that could work in his favor. Strong value threshold: middle of round 2.
