Isn't it maybe time to give the referees a hand by either
allowing the linemen to take some of the responsiblities for making
calls or adding another referee. I have a very good friend who
officiates high school football, he constantly hears the same complaints
about missed call and lacked inforcement of the rules. His response is
that how can 4 officials SEE the same as 10,000 fans. His other response
is that NO official worth his weight will blow a "equalizing" penalty
just because he missed a call. I think the point is that it is just
too hard to see all the action when you are just one man.
