I gotta respectfully disagree. My interpretation of the rule (and it looks like this officiating crew agrees with me) has always been that the player who touched the ball last "caused" the ball to go into the backcourt. Just because Butler's swipe knocked the ball into Monk's knee doesn't mean that Butler "caused" the ball to go into the backcourt; Monk's knee did that.Correct. Butler caused the ball to go into the backcourt, the call was (yet again, shockingly) in error in the other team's favor.
