This is part I of volleyball coaching legend Mike Hebert's blog series on his pet peeves. Check back every Friday for his next entry!

From my first experience as a Santa Barbara-based beach volleyball
player in 1962 through my most recent coaching stint at the 2011 Pan American
Games—some 51 years in the game—I have seen and heard it all. I was there when
the rules of volleyball in the US permitted back row players to participate in
the block. Screening for the server was also popular. All five players would
stand shoulder to shoulder as the server launched the ball from behind a tight
wall. And then there was the synchronized
hand clap by teammates at the exact moment anyone executed an overhand pass or
set. The sound of the hand clap prevented the referee from hearing the noise
created by an unclean contact of the ball, thereby side-stepping a possible
ball handling violation.
I can also remember when the block counted as the first contact, severely limiting the effectiveness of the counterattack game. While at UCSB’s Robertson Gym in the mid-60’s I learned how to hit a “Jap” set, which is what everyone called the quick “1” set pioneered by the Japanese men’s team at the 1964 Olympics. There was even a time when spikers were not allowed to follow through over the net with their hitting hand. And you really missed out if you were not around when it became legal to block and attack the serve!

By the 1970’s and 80’s the game as we know it today began to
take shape. The block no longer counted as the first contact. Antennas were
added to the net. Sound was ruled out as a reason for evaluating the quality of
a contact. No more blocking or attacking
the serve. No intentional screening. Only front row players could block. A
player could initiate serve from anywhere on the baseline. No double contact
called on a player who is defending against a hard driven ball. Contact with the
net was now legal under certain circumstances. The libero position was
established. And, most significantly, the game was changed from side out to
rally scoring.
It is my opinion that, as a result of these changes, our
game is in much better shape than it has ever been.
However, should there be a remote chance that any of you
might be interested, I have identified a few things about our volleyball
universe that “bug” me. So, if you will allow me to reach into my pocket to
unfold my tattered list of volleyball pet peeves, I will share some of them
with you. The list is a work in progress. Sometimes I draw a line through an
item when I decide it no longer warrants pet peeve status. And sometimes I add
an item to the list when I notice something that causes the pet peeve warning
light to start flashing. If only these items could be resolved, I
self-righteously say to myself, our volleyball world would be a better place.
1.
Why do volleyball people attribute meaning to per set statistics? I read discussions
on volleyball chat rooms where contributors argue that Team A is a better
blocking team than Team B because they average
more blocks per set. Even worse, per
set statistics are used to evaluate All-Region and All-American candidates!
Here is the problem. The top team
in a conference (Team A) can play against the last place team (Team B) and win
in a 3-0 blow-out. As a result, both teams participate in a relatively low
number of total rotations, thereby limiting the total number of blocking
opportunities available to each team. Both teams’ blocks per set will be low
when compared to the totals accumulated
in a match between two evenly matched teams where the score can be 3-2,
and the total number of blocking opportunities much higher than the earlier
example.
Consider that the first place team
will likely play in a higher number of 3-0, low rotation matches and might
average, say, 1.7 blocks per set. Another
team, which competes in more 3-2 and 3-1, high rotation matches can average,
say, 2.2 blocks per set…not because they are a better blocking team, but
because they play longer matches that provide significantly more opportunities
to post a blocking stat.
All per set statistics suffer from the same flaw. Only per attempt statistics have value. And the
only per attempt statistic available
to us is Kill Efficiency. Our sport needs to overhaul its approach to
statistical evaluation to rid itself of per set stats. How many times do I have
to listen to someone tell me that blocker A is better than blocker B because
she has a higher blocks per set average. Blocker A plays on a powerhouse team
that wins most of its matches 3-0. Blocker B, on the other hand, plays on an
average team that battles its way to 4 or 5 sets virtually every time they
play. It is conceivable that Blocker B can post a higher blocks per set average
merely because she plays on a team that provides her with more opportunities to
block.
Further complicating this issue are the following:
a.
Some teams prefer to use their block to channel
the ball to their diggers. They are likely to block fewer balls simply because
of their system.
b.
Others want to block every ball they can with
less concern for channeling. to diggers. They are likely to have higher blocks
per set numbers; again, because of their system.
c.
Some teams emphasize control blocking, making it
possible to pass the ball accurately to
their setter for a counterattack opportunity. This can be a very effective
system choice, but there is no stat recorded for a control block.
d.
Some teams are very physical and can put up an
intimidating block, forcing the opponent’s attacker into a tip or roll shot which
is easily scooped up by the blocking team. But again, no blocking stat is
posted.
All of the above have a significant impact on the accumulation
of blocks per set. But they lead to a wide variance in team blocking totals.
They are an unreliable indicator of which teams are the better blocking teams.
There is no scientific correlation between the blocks per set statistic and the actual blocking ability of a team.
