Blocked shot with contact

[Rodical]

I try to see it as any other contact....advantage/disadvantage.....if there is slight contact that is incidental to the play...no foul...if the defender's momentum carries him into the shooter, so that it seems obvious that without contact he would not have been able to block that shot, then it's a foul. When in doubt, I blow the whistle, since these things can escalate quickly.
