I get tired of this argument, so I'll just let the numbers speak for themselves. (source, ProFootballFocus for pressure and total snap numbers, without pressure numbers are my math)
In the NFL last year-
Comp% (Total Completions/Total Attempts)
2012 Total - 60.9% (10,825/17,779)
QB NOT under Pressure - 66.1% (8,690/13,154)
QB Under Pressure - 46.2% (2,135/4,625)
According to the legendary PFF, 31.4% of NFL snaps last season came under pressure. 26.0% of NFL pass attempts came under pressure (the difference of 5.4% is due to sacks and scrambles).
I'm focusing specifically on the attempts that came under pressure where there were not sacks or scramble attempts vs normal attempts.
TD% (Total TD) - Int% (Total Int) - TD:Int ratio
2012 Total - 4.2% (755) - 2.7% (486) - 1.55 Td:1 Int
QB NOT under Pressure - 4.6% (605) - 2.4% (311) - 1.95 TD:1 Int
QB Under Pressure - 3.2% (150) - 3.8% (175) - 0.86 Td:1 Int
So, as you can see, when a QB is under pressure, he loses 20% (66.1% vs 46.2%) in completions, loses 30% of his ability to throw a touchdown (3.2%/4.6%), gains 60% (3.8%/2.4%) more likelihood of throwing an INT, and his ratio of TD:Int drops by more than half (1.95 / 0.86).
Do I think pressures matter? Yes. If you don't, I'd really love to know why.

Al was old school and didnt need all the math to figure that out. but thanks.
To address Fresh's question in another thread about "pressures" and "10 minutes to take a pressure, does it still count?."
All I can say is, the starting QBs in the NFL averaged 2.5 to 3.0 seconds per pass attempt. In your 10 mintues, every starting QB in the league would get 200-240 pass attempts off in that time.
I agree, but some people on this board are stupid
(source, ProFootballFocus for pressure and total snap numbers, without pressure numbers are my math)Another PFF reference? Shocking...
So, what's time window for pressures?10 minutes.

So you can get 1 in a season?10 minutes.
Franchise me up, bro
Looks like during that time period, with a dead QB, you'd get yourself a tidy 5 pressures. Clearly we are talking apples to apples here.Sorry, a total of 5 pressures for your 3 fat lineman. So maybe one of you will get 2.
And what does it matter? The same way they measure the pressures shows that a QB goes from 66% to 46% completions when pressured. I'm sure it's even lower when they get to the QB right away.
The pressure stat doesn't have a time window from what I can see
Congrats! You were the 1st guy to get there in under 6 seconds
Hoof'nray you got to the QB when he was on his 700th read. You've been awarded a pressure!
Right or wrong? Am I wrong in thinking this particular stat is radically incomplete?
Just because you ALMOST get there doesn't mean you should get sack/fumble money
Pressure is simply forcing the QB to throw early or rushing his attempt in progress. Helps to bring down his accuracy. Not every time but over the course of a season it brings down their completion percentage and helps force mistakes.
Obvious stuff for sure.
And what does it matter? The same way they measure the pressures shows that a QB goes from 66% to 46% completions when pressuredIt matters because this is a potentially misleading stat. If a QB drops back and goes through his 3rd and 4th reads before anyone gets there, the guy who finally shows up at the end will get credit for a "pressure" when he really didnt do shiz.
I'm sure it's even lower when they get to the QB right awayWhich is exactly why this stats is misleading. The guy who gets there in 2 seconds gets credit for a pressure just like the guy who didnt get there until 5-6 seconds. The guy who got there late was only able to "pressure" the QB after there was no where for him to go with the football because of decent coverage.
Just because some pressures take 6 seconds and saying they are invalidated is like saying quick sacks don't count because sometimes the QB falls and the defender just bumps himIf a QB slips and a defender is close enough to be Johnny on the spot to get the sack then he did a good job for being in a position to make a play. Making a sack that ends the play will ALWAYS be more valuable than just getting a pressure that "might" help you out.
