text: what are at least 5 rules in football?   (1)  false start - the most common.  too many of these are called.  i wish they would change it where it is a penalty only if the person is crossed the line after the ball is hiked (2)  offsides - this used to be the most common, but has been overshadowed by false start.   (3)  holding - whether offense or defense.  i'd like to see this change, too.  considering how violent football is, 'holding' is almost funny (4)  pass interference - the harshest of all penalties.  i think they do a pretty good job calling this (you must go after the ball, not the receiver) but having a hand on the receiver should not be called pass interference (5)  neutral zone infraction - after all the years i've followed football, i cannot adequately explain this.  they treat it like nba basketball, where you cannot just 'wander' into a particular area before the ball is hiked by the other team.  dumb dumb penalty
