Derrick Jones Jr - is the improvement real?

[Dundalis]

If he was more reliable from the 3 point line, he'd be a very solid starter on a contender. But even though he's basically only taking wide open 3's, he's as inconsistent with hitting them as a good shooter is on contested 3's. He's still a clear better option than Green to start, but the teams primary need outside of a true backup 5 is a long defensive wing, who ideally starts in his position. Him, Green and Exum as bench unit perimeter lockdown option would be ideal.
