As was discussed in a different thread, when is R given the benefit of clean hands....The NHFS has stated that if R fouls after the ball crosses the ENZ then they are considered to have gotten the ball with clean hands....Jrut, thanks for pointing me to the NHFS site, I didn't find a CD but I did find a powerpoint presentation... anyone that is interested, go to this link and look for slide 14 for this specific point but the whole thing is a good tool
