Young has actually outscored and outshot Dawkins this year in d-league, and he's only 19 to Dawkins's 23.
Young also likely just slipped out of the lottery at age 18 due to his auto accident, after proving his top-tier team's go-to scorer in the collegiate postseason, compared to the undrafted Dawkins, who never scored for a double digits average in four years of college.
So I'd say there's not really evidence that Dawkins is a better shooter than Young. He's presumably much more seasoned, while Young has the much higher upside.
