is this a foul?

"contact that does not hinder normal offensive or defensive movement is incidental"

Agree, of course, with your definition of incidental contact. Isn't that what we're debating -- whether it did hinder normal offensive movement? If the offensive player has to alter the shot or the motion to avoid an onrushing defender who cannot avoid making contact, why is the only advantage/disadvantage question how siginficant the contact was?

Incidentally, arent' there some definitions of "incidental contact" -- maybe the NBA's -- that exclude contact that affects a player's "rhythm"?
