He’s garbage if the only way he can get playing time is when a undrafted guy is injured.
Not in all cases.
But, in this one, yeah.
He will go back to dnps.
I'm inclined to agree that he's unlikely to sustain his current level of play when the guys who are out return and regular rotations are being used again.
But all that really matters is that he has stepped up now and is part of why the Lakers have managed to more or less "tread water" while AD has been out.
