The two best examples from last year
are probably Ryan Grant and Brandon Jacobs. In 2008, Grant touched the
ball 330 times but he had only 5 touchdowns. Because of that, he was
being taken as the 16th running back despite excellent
rushing statistics and was behind Brandon Jacobs who was 12th.
Jacobs had a very good year with 1,089 rushing yards in only 13 games
and he also had 15 touchdowns in only 225 touches. Jacobs had finished
with 30 more fantasy points than Grant despite playing only 13 games so,
of course, he was getting drafted ahead of him. However, if you looked
closely, you would have noticed that Grant had 30 more fantasy pts than
Jacobs if we excluded their fantasy pts from TDs.
In 2009, Jacobs finished with the
exact same number of “non-TD” fantasy pts than the year before and Grant
had only 20 more than the previous year. In total fantasy points
however, instead of a change of 20 between the two, there was a change
of 110 fantasy points in Grant’s favor! How did that happen? Jacobs went
from 15 touchdowns to only 6 and Grant went up from only 5 to 11. That’s
a difference of 90 fantasy points simply because of touchdowns. The
change may have been much more than we expected but the formula
predicted a change of 50 fantasy points in Grant’s favor which was
enough for us to rank him above Jacobs last year. Because of that
theory, Matt Forte and Steven Jackson are underrated this season while
players like Michael Turner and Jonathan Stewart are overrated.

As you can see, wide receivers have
the most inconsistent numbers compared to quarterbacks and running
backs. The formula is: 0.062 + 0.271 x previous year’s ratio.
In 2008, DeSean Jackson had 62 catches
for 912 yards and 2 touchdowns and in 2009, he had only one more catch
but he had 250 more yards and 7 more touchdowns. There are 19 receivers
who, since 1983, have had a TD to receptions ratio of under 0.06 and
went up to over 0.12 the following season (like Jackson). The following
year, their average ratio was 0.091. This means that if Jackson once
again has 63 catches, he should only have 6 receiving TDs instead of 9
which would give him 18 fewer fantasy pts than last year. If we also
account for his yards per reception average, which went way up, (and
usually follows a similar trend than the TD to receptions ratio), he’ll
probably have 25 to 30 fewer fantasy points than last year. He went up
from 31st to 11th last year while catching only
one more pass and yet fantasy players are still drafting him as the 7th
best WR. Touchdowns are extremely inconsistent and because of that,
DeSean Jackson is extremely overrated this season.
The data is a little too limited to
come up with a formula for tight ends but I assume that this would also
apply to them. Some of the tight ends that had high ratios that you
might want to be careful with are Vernon Davis and Visante Shiancoe
while players like Jason Witten and Zach Miller could improve over last
year.
In conclusion, I hope this article has
made you understand that players with a lot of touchdowns will not
necessarily be able to repeat those numbers in the following season and
you should not assume that they will. When you are studying a player
and deciding whether or not to draft him, take a look at his touchdown
number and keep in mind that it will likely vary much more than his
other statistics, especially his number of carries and receptions.
This ratio is included in our
2010 Player Rankings and for those
players where we are far away from other sites, compare our projections
for TDs and it'll likely explain a lot of things.
