1. This was bang bang. Ref called the foul within a second
2. Ref didn't have the angle? No way the ref on the baseline sees this. Your argument is thin

The continuation signal is made whenever the foul takes place while the shooter is in a shooting motion, whether it is on ball or off ball.
Ref is clearly looking right at Gobert being fouled.
There is no evidence that he was calling a foul against Mitchell when nobody is within 5 feet of him,
