last year in NCAA,but looking for ruling in NFHS and can't find. Team A is up by 2 with 1 second left, A1 is trying to miss FT, but right before he shoots everytime, B1 keeps putting his foot in the lane to create delayed defensive violation. How long do you keep calling it before you warn team B and assess a technical???? Can you warn team B there are making a mockery of the game at some point and assess team B a technical?? If so, can you help me where to find in book?? Thanks
