I feel compelled to mention that I didn't hear the audio for myself, so I cannot personally confirm that any of this happened, but it looks legitimate.

Tyler Johnson could miss the rest of the season with a torn rotator cuff in his left shoulder, but he is a good player, averaging 8.7 points, and 2.2 assists on on .488 shooting from the field, and .387 from three. He is someone I'd welcome if added to the Kings roster, but wouldn't seriously entertain swapping Casspi out to get him, especially with his health in question. The Kings need help now, and Johnson won't be able to do that.
