he looked dangerous, and put the wind up our defense whenever he broke forward. Suppose his coaches need to drill him about the final pass/shot, otherwise he'll always be a change of pace sub, who doesn't actually achieve much. He's only 20 so he's got a bit of time to improve...
That's what he did last season (when not injured).
Comes off the bench for 10-20 mins. A couple of amazing runs - no end product. Disappears.
