No offense taken, always question numbers, especially when a source was not cited.
My source for stats is

STATS Inc. does the stats for ESPN by the way.
According to their "Glossary of Statistics" a dropped pass is:
"Any incomplete pass which was catchable with normal effort. STATS compares and reviews the judgement of multiple reporters to determine if a pass was dropped."
So I guess a pass that was three feet too high that had the reciever stretch out and just barely have it go off his finger tips is considered a poor throw since normal effort would not have been able to catch the ball. It's not to say the ball is totally uncatchable.
By viewing an individual receivers stats you can scroll to the bottom of the page where there are incompletion statistics. All I did was subtract receptions from "thrown to" and now we have the number of incomplete passes thrown at that person weather they were INTS, just plain incomplete, or dropped.
I admit I may have made mathamatical error so check it if you want. In fact, I'd recommend checking them.
Also, you can look at a QB's stats for incompletion statistics too.
40.9% of Blake's incomplete passes were attributed to "poor throw", these poor throws make up a whopping 17% of his total thrown passes, or a little greater than one in six.
18.9% of total incompletions were passes defensed, 9.4% were picked, 3.1% hit at the line, another 18% were "other" whatever that is, I am guessing "getting rid of it" and spiking the ball, and 8.8% of the time a pass is incomplete it was because the receiver dropped it.
McCown isn't much different percentage wise but he had far fewer tosses of the rock. One thing that does stick out is 18.3% of his incompletes were dropped.
Interesting to see how much of a problem drops are this year.
Finally for anyone interested I also visit a site called footballoutsiders.com that has a unique system for evaluating statistics. The basic idea is that a play is either successful or unsuccessful depending on the situation (down and distance). Lots of other stuff is included and to really understand it you'd have to go to the site and read the explanations. Some people there are expecting us to make a playoff run in the next 2-3 years, so we are turning a few heads.
Looking at the recievers, you see that despite the "pretty" stats Quan accumulated they really didn't do much in regards to actually making our offense efficient. I know. Heresy you say, but please don't revoke my membership from the Cult until you go to the site.
Looking at the list you see Quan was just about average (slightly below) but Johnson was third worst amongst recievers thrown to 50 or more times.
Again I may have made a mathamatical error when I was doing this stuff so check it. I am certain that I did them correctly though.
