I remember someone asked Babb who was the next lock down defender under Fred and he said Naz
Even if he doesn't start or get major minutes this year, I could see him being used at the end of close games when we need someone to harass the opponent's PG. He would be fresh and bring that defensive intensity, but also let a scorer take a little breather before they come back in to hit clutch shots. He and Kane look like they could be quite disruptive on the court at the same time.
