The five second rule which I rarely have ever seen called is one that I have never understood at all. Not the out of bounds one. This one= The official(s) will visually commence a five-second count if an offensive player with the ball and not facing-up starts dribbling below the free throw line extended while being closely guarded; or if he starts dribbling outside and then penetrates below the free throw line extended while being closely guarded. The five-second count commences when the offensive player penetrates the free throw line extended. The penalty is the offensive teams loss of possession of the ball." This is not the same as the Mark Jackson rule.
