Evan Mobley’s subtle star power set USC on a path for March, but Isaiah Mobley’s sudden rise down the season’s final stretch elevated the Trojans to another level in the postseason.

Isaiah’s performance was impressive enough for him to seriously consider joining his younger brother in the draft. Evan was selected third overall by the Cleveland Cavaliers, while Isaiah chose to return, aiming to become the focal point of USC’s offense.

His defense, Enfield says, may be even more important.

“We feel that Isaiah has turned into what I think is the best defensive big man in our conference,” Enfield said.

That would go a long way in replacing his brother, who averaged nearly three blocks per game on his way to Pac-12 defensive player of the year honors. But USC still has plenty of size in its frontcourt, especially with the addition of 6-foot-11 forward Josh Morgan in the frontcourt. Morgan sat out last season after transferring from Long Beach State.

The better question might be how Isaiah Mobley will handle being at the center of it all. He seemed just fine in March, when he shot 66.7% from three-point range through the postseason. Enfield said he’s developed into “a true inside-outside player” and “a great passer.”
