Is Cooper Flagg being overrated defensively?

Don't get me wrong he's definitely a good defender and he should easily be a plus defender in the NBA but I don't really see him being some special outlier defender like AK-47 or Scottie Pippen, guys he's often compared to defensively. I don't see him challenging for DPOY or even all-defense. He'll be a solid, versatile defender similar to Jayson Tatum. His stock numbers are solid but nothing crazy (1.1 blocks and 1.6 steals per game). He has some questionable discipline at times, especially on close outs, and he gets blown by pretty easily by smaller players.

I think he earned this reputation as a defensive phenom when he played 16U EYBL when he played as a center against kids mostly much smaller than him, so he was able to rack up some crazy block numbers, but I don't think that level of defensive dominance has translated against better competition.
