ESPN Insider's Chad Ford and Kevin Pelton return to provide the kind of discussions that are happening in front offices around the NBA -- where scouts and statistical experts are breaking down NBA draft prospects using their "eyes, ears and numbers."

Question: After combo guard D'Angelo Russell, Arizona forward Stanley Johnson is the top-rated American wing on Chad's big board (10th). How good is Johnson?

Kevin Pelton: I have Johnson rated a little lower. He's 19th on my first statistical big board of 2015, though there isn't a great deal of separation between 11th and 24th and Johnson could land almost anywhere in that group. The big factor working in Johnson's favor right now is his age. He won't turn 19 until May 29, before the draft, making him the second-youngest prospect likely to go in the first round (Kentucky's Devin Booker is the youngest; he turns 19 on Oct. 30). But based on his performance this season, I project him to be about replacement level when he enters the NBA. Is that reasonable?

Chad Ford: There's an interesting split on Johnson among scouts and execs.
