Foul called after shot. . .

[mplagrow]

Had a sitch today that I don't think was right, but here goes. Yes, I ref, but today I was coaching 8th grade boys.

A23 (my team) puts up a floating three pointer. Whistle blown late, Lead calls push on A31 'after the shot'. He calls the basket good, and gives B the ball OOB.

Correct me if I'm wrong, but that's not possible, is it? If I understand the rules, this is what it should have been:

1) the foul was before the basket, so dead ball
2) no foul, just incidental contact after the basket,
3) the foul was intentional after the basket.

I didn't point it out to the ref, because if I did he probably would have said, "OK, coach, I'll change it to intentional if it makes you happy!" Probably what I would do! Thoughts?
