Your positioning, your mechanics, and your hustle on this play all look great.
I spent some time reflecting upon jersey holds a few years ago and concluded that it is best to deem them intentional fouls as a past NFHS POE advocated.
These are non-basketball plays and should be penalized severely.
Great work catching the action. I can understand how the old Trail didn't see it because he would shift to looking at the location of the loose ball, but I believe that the old Lead should have also been able to see this, IF he knew that the ball had been knocked loose and shifted his eyes up the court. However, if he was focused in his PCA still thinking that the white team had the ball, then he may not observe it.
Do you know who else had a perfect view of the play? -- the Head Coach for white standing just to your right.
Overall, nice work. I would only suggest that you spend some time thinking about whether to call intentional personal fouls on plays such as this.
