Yeah, Grantland had a similar piece on the Okafor/Porzingis matchup. Sounds like he (or the coaching staff) made some adjustments to start fronting Okafor in the second half and it worked better than getting constantly backed down under the basket.
Of course in the NBA, he'll probably never have to guard someone like Okafor anyway so it is moot. But it's good for development.
