From the video

Once Coleman's past the line of scrimmage, he has to learn to leverage his size and get downhill fast. He's too prone to bouncing plays with outside pursuit. And he ends up slanting inside thinking that he's going to find openings against the grain of the defense's flow. And he's just not that explosive or that agile to to do this.
STACKED’s take
Negative signalRole
Coleman lacks explosiveness to execute his cutback instincts; too easily tackled for his size.
Coleman must learn to leverage his size and get downhill fast once past the line of scrimmage. He is too prone to bouncing plays outside and slanting inside looking for grain-against openings, lacks the explosiveness and agility to execute this, and gets tackled too easily for his size instead of sticking his foot in the ground to force pursuit angles that won't bring him down.
