Be the Referee: Blocking Below the Waist
November 13, 2014
This week, MHSAA assistant director Mark Uyl explains the differences between high school and the college and professional games when it comes to blocking below the waist.
"Be the Referee" is designed to help educate people on the rules of different sports, to help them better understand the art of officiating and to recruit officials. The segment can be heard on Mondays, Wednesdays and Fridays during the school year on The Drive With Jack Ebling on WVFN-AM, East Lansing.

Many times the key rules differences between high school football and those rules used at the college and profession levels deal with player safety. One of the best examples of this deals with the rules that cover blocking below the waist.
All of us have watched that game played on Saturday or Sunday; we’ve seen that wide out or the wide receiver blocking downfield, and they block the defender below the waist in springing that runner for a big gain.
At the high school level, the only offensive players that can block below the waist are those on the offensive line, generally positioned from tackle to tackle, and those blocks below the waist must be immediate – at the snap – and within that free blocking zone at the line of scrimmage.

Be The Referee is a series of short messages designed to help educate people on the rules of different sports, to help them better understand the art of officiating, and to recruit officials.
Below is this week's segment – Volleyball Differences - Listen
The very first MHSAA Boys Volleyball Finals are less than two weeks away. How does boys volleyball compare to girls volleyball in terms of rules and gameplay?
Very similarly. There’s really just one difference – the height of the net.
- The girls play with the top of the net set to 7-feet-4 and 1/8 inches.
- The boys play with the top of the net set to 7-feet-11 and 5/8 inches.
A difference of 7½ inches.
But other than that, the games are the same. Same size ball. Same size court. Same number of players. Same scoring system.
And all rules pertaining to the libero, multiple contacts, player position at moment of serve and unplayable areas are the same for both.
Now you’re ready for Battle Creek and the Boys Volleyball Finals.
