Rookie Wide Receivers
The 2010 National Football
League Draft took place once again at the Radio City Music Hall in
New York City in late April. Year after year, once the draft is
completed, analysts try and determine who were the winners and
losers on draft day. Once training camps begin, fantasy sites and
fantasy football managers try to predict what impact newly drafted
rookies will have on their new teams. I was curious to find out
whether rookie players were generally overrated or underrated by the
average manager in fantasy drafts. In this article, I will compare
the average draft position for rookie wide receivers to their end of
year ranking in fantasy points (in a points per reception scoring
system) in order to determine whether or not rookie wide receivers
are worth drafting.
For this analysis I decided
to look at wide receivers drafted in the first four rounds of the
NFL Draft since the year 2000. To be part of this analysis, the wide
receivers had to have been drafted in at least 5% of fantasy drafts
according to data from
myfantasyleague.com and had to play in at least one NFL game in
their rookie season. This left us with 78 rookie wide receivers to
analyze. As mentioned in my introduction, in order to determine if
rookie wide receivers are generally overrated or underrated, I am
comparing their ranking amongst other wide receivers before the
season (average draft position) and after the season (fantasy
points). Of the 78 rookie wide receivers since 2000, 33 of them
performed better than their average draft position which is equal to
42.3%. On the other hand, 40.2% of the non-rookie wide receivers
performed better than their average draft position since 2000. As
you can see, by drafting a rookie wide receiver, your chances to
make a good pick are 2.1% higher than by drafting a non-rookie wide
receiver, a pretty negligible margin.
It is evident that players
drafted later in fantasy drafts are more likely to improve than
players drafted early because they have more room to improve. One of
the problems with the data presented above is that the average draft
position of rookie wide receivers is 61.7 while the average draft
position for non-rookie wide receivers is 42.3. Therefore, instead
of comparing the rookie wide receivers with all wide receivers, I
thought it would be fairer to compare them with only the wide
receivers that were between the 39th and 85th wide receivers taken
in fantasy drafts. This ensured that the average of the average
draft positions for both groups would be around 62. By choosing only
that group of wide receivers, the percentage of non-rookie wide
receivers that improved increased from the original 40.2% to 46.5%.
This means that your chances of making a good pick in your fantasy
draft decrease by 4.2% when you choose a rookie wide receiver over a
non-rookie wide receiver, not a huge difference.
