I realize that. I'm talking about on a try for goal when the defender attempts to block the shot. If he hits the rim or net when attempting to block the shot we have BI, assuming the other factors are in play. Why not the backboard? I agree by rule we have nothing. But logic says it is basket interference. Again, I'm not talking about intentionally hitting the backboard.
