Not randomly. He has always had the potential to be a good defender (check out his pre-draft notes, his NBA player comp is Amdrew Bogut) he just played with DLo, Teague, Wiggins etc who just pretended to be matadors and would Ole people at him uncontested as the rim protector. Now he is the help defender instead of the sole rim protector and we have guys like Ant, McDaniels and NAW to hound PoA players.
