USC Passing
Distribution 2001-2006
In
an different post I put up the receptions trend for the USC Tight Ends
and Fullbacks in recent years. It is useful to look at the overall
trend for receptions and distribution as well. The following charts are
an imperfect look at how USC distributes the ball on offense in passing
situations. I will note the inherent problems below in this chart...but
first the data.

As you can see the numbers are fairly stable
after the 2001 season. Each year varies slightly of course due to the
depth and experience at quarterback, wide receiver, tight end, running
back, as well as the offensive line. 2006 was an "average year" in
hindsight with a slight drop off in yards per completion and total
yards.

What
I thought would be more interesting is to see what position is catching
the ball the most in each year. As you can see in this next chart it
bounces around a bit but not too much. The WR's caught the majority of
the passes in in every year and in 2002 the WR's caught 203 of the 313
completions. Of course this tells us nothing of where the ball was
thrown on the field. That would take more film breakdown and tracking
to see if the pass was a screen play, a slant route, a post route, or a
hitch route for example. But this shows a few things of note. One
example is that in 2004 when USC was the undefeated national champion
they utilized the WR's less and threw to the tight ends more. The
reason was that Steve Smith broke his leg and the coaching staff ran
more routes and plays for Alex Holmes and Dominque Byrd out of
necessity.
In 2006 we can see that the WR's again took the lions
share of the receptions. The big drop off was in the area of pass plays
to the fullback and tailbacks. The reason was probably two-fold 1)
injuries to the fullbacks and 2) a younger backfield in general. In
2007 this number will probably edge back upwards to a more normal
range. Steve Sarkisian has commented in the offseason that he'd like to
use more two back sets (e.g. I Formation Plays) and this will probably
mean more play action passes and short throws to either the FB or RB
out of the backfield. The incoming freshman Joe McKnight will make
things interesting as well with his receiving skills.
One
inherent problem in this chart is the following. It merely lists
receptions by the "home" position of the player by year. Reggie Bush
caught passes out of the backfield but also caught passes while lined
up as a wideout. This simple chart does not reflect that more complex
reality. So for 2004/2005 seasons when Reggie Bush caught about 40
passes per year this would mean shifting perhaps 15 or so completions
out of the RB segment and up into the WR segment. Also as stated above
this graph doesn't tell you where the ball was thrown on the field
either (short, medium, long, left, middle, right, etc.). However it
gives you a *rough* idea of where passes went and how the distribution
has slightly changed. We'll check this at the mid-point of 2007 and see
where things stand next season.
