LOS ANGELES — Ja Morant grabbed a seat in the gymnasium bleachers at a Los Angeles-area high school following practice with the Memphis Grizzlies on Monday afternoon. It was a rare moment when he was not in motion. A rookie point guard, he tends to play with the smooth, relentless rhythm of ocean surf.

Morant just keeps coming — at defenders, at the basket, at the lofty standards he sets for himself — and he has already done a good deal to validate the Grizzlies’ selection of him with the No. 2 pick in the N.B.A. draft. Entering Saturday’s game against the Phoenix Suns, he averaged 17.5 points and 5 assists while shooting 50 percent from the field and 42.9 percent from 3-point range .

But as fast as he plays, and as seamlessly as he has made the transition from Murray State to the N.B.A., Morant is still absorbing some of the most fundamental lessons about life in the league. Near the top of that list: The schedule seldom slows. Game after game. Road trip after road trip. Tough assignment after tough assignment.

“Just how quickly you need to turn the page,” Morant said. “You can’t worry about the last game so much, because you’re always moving on to the next one.”
