Did LeBron mock Lonzo Ball's shooting form?

LeBron James appeared to be making fun of the shooting form of UCLA's one-and-done star Lonzo Ball before the Cavaliers-Bulls game on Thursday. The moment was included in a video shared by the NBA.

The full video seems like a pretty normal 50 seconds of warmup footage, but Sports Illustrated noticed this:

LeBron may deny mocking the 19-year-old, but what he was doing looks very much like Lonzo's extremely unique shooting form.

This comes a week after LeBron issued a stern warning for Lonzo's father, LaVar Ball. The warning was a response to comments LaVar made in which he said that LeBron's kids are going to have a tough time living up to the expectations set by their dad.
