LAS VEGAS — Summer league is about trial and error.

And the Knicks, as a whole, experienced more error than accuracy while getting outscored by a combined 31 points in their first two Vegas games. The starters have been overmatched.

But in the case of reserve Mohamed Diawara, there have been enough promising moments to at least see the vision.

“I’ve been really impressed with Mohamed,” Knicks summer league coach Jordan Brink said. “His ability to rebound and run, to push off misses and makes. I thought he was really solid [in Sunday’s loss to the Celtics]. Pretty active defensively, still learning the defensive system and low-man principles.”
