In order to test this, I used statistics from
the 2008 season and created two teams of nine players (one QB,
two RBs, three WRs, one TE, one K and one D). Both teams had the
exact same total number of points from week one to week sixteen
but one team was very consistent while the other was very
inconsistent from week to week. The first team had an average
coefficient of variation of 0.38 while the other team’s average
coefficient was 0.60. Afterwards, I used a function which
randomly selected a point total for each player from the fifteen
possible (week one to week sixteen minus bye week). For example
I may be using player A’s week six performance, player B’s week
three performance, player C’s week nine performance and so on
for all nine players on the team. I did that for both teams and
matched up the two teams against each other 500,000 times using
different combinations. Here is a summary of the results:

Team A |
0.36 |
255,619 |
51.12% |
|
Team B |
0.64 |
244,122 |
48.82% |
(CV for
an average fantasy team is about 0.53)
As you can see the more consistent team wins
more often but it only has a 51.12% win percentage versus 48.82%
while tied games were 0.06%. To put this in perspective, I
created two more fictional teams that both have the same
consistency but every player on one team averaged 0.2 points per
week less than the other (3 points per player so 27 points less
for the entire team). The team that averaged only 3 points per
player more won 52.36% of the time.
This study shows that you are much better off
focusing on drafting better players than drafting consistent
players as it barely has any impact on your fantasy team’s
overall performance. This does not even account for the fact
that it is quite difficult to predict a player’s consistency
from year to year. If we assume that: you can predict how
consistent a player will be from week to week and you can draft
the most consistent players on your team, your advantage will be
the equivalent of about eight fantasy points in a season or
less than half a point per week for your entire team.
There is no statistical evidence that shows
you should stay away from Terrell Owens or Randy Moss because
they are inconsistent players. Although in theory a more
consistent player should help your fantasy team win more games,
with nine players on your team there are always some that will
have good weeks and bad weeks so it neglects the effect of a
single player’s inconsistency. Moreover, there are no NFL
players that are consistent or inconsistent enough from week to
week for this theory to have a real impact.
In conclusion, if another manager in your league says he is
staying away from Randy Moss because he has a low “Crank
Score”, give him a fake smile and be very happy to draft him
(if he’s the best player available of course).
