Would you call a foul if it will give disadvantage to the team fouled?

A few years ago, I was working a JV boys game. First half, A1 caught a pass in transition between the table and B's bench and immediately passed to a wide open A2. I called a foul because B1 came up and bumped A1 pretty good (displacement of a couple of steps due to the contact).

I wish I'd had that one back. A1 completed the offensive movements he was trying to do, and it should have led to a wide-open layup if I'd seen the big picture.

No, I'm not going to wait to see if a basket is made on a potential shooting foul, but I will process whether I think the contact had any significant impact on the difficulty of the shot. In my case, the pass was gone before the contact was made, there was no need for that call.
