PFF's Cornerback stats for the year

by Cory Braiterman on Jan 19, 2012 12:01 PM EST

As some of you may recall from the comments sections in the weekly PFF grades, I'm not a huge fan of their somewhat arbitrary number grading system that doesn't seem to match up with what we just saw most of the time. Statistics, however, are something I can get behind, as there's no opinions to be had with numbers, they're just there. You can form opinions on them (and should), but in and of themselves, they're just there.

Incidentally, that's part of the reason I dislike their number grading system, as it seems to not actually be based on reality, and numbers tend to indicate fact rather than opinion.

Whatever, let's check out the only Giant to make this post of best and worst CB's when looking at completion percentage, yards given up and QB rating.

Now a lot of factors aren't taken into account, such as safety help, playing nickel, etc. but at least to me, these are about what I expected when I think of who're "good" and "bad" CBs. Aaron Ross was the only NYG mentioned (aside from Corey Webster being targeted a lot), and it wasn't good. He had the 6th worst completion percentage, with QB's landing an unsightly 67.9% against him. It wasn't just a small sample size, either. Of the ten worst Comp% CBs, only DeAngelo Hall had more attempts at him. He was also #9 in yardage yielded, despite being the least targeted CB amongst the 10.

Finally, QB's had a fairly disgusting 102.8 rating against Ross, bad enough for 10th worst out of the 66 CBs included in this list. Not as bad as Quentin Jammer, who had a barf-worthy 129.9, but pretty bad in and of itself.

On the other side of the coin, it should come as little surprise to the objective observer that names like Darrelle Revis (#1 in both QB % and rating), Asante Samuel (8 and 2), Ike Taylor (2 and 4), Chris Gamble (4 and 3) and Brent Grimes (3 and 10) top this list, as they are counted amongst the top cover corners in the league. The only surprise to me is that Nnamdi Asomugha didn't make the top 10 in either stat. He had a somewhat pedestrian 571 coverage snaps, targeted 47 times, allowed 29 catches (61.7%), 376 yards, QB rating against of 88.6.

Remember Stats only tell the person what they think they saw

which by definition is opinion based… Not knocking your post. Our defensive secondary was a wreck for whatever reason, for a majority of the season.

I know a lot of people like to knock Ross, but the only completions I really see him give up are when he is covering a Zone. No qb has challenged Ross while in man, since the Rams game. That to me is a sign of a good-great CB.

then you look at PFF, and it tells a completely different story.

Regardless of what happens, No playoffs, playoffs, no superblow, superblow.... The 2011/2012 is one of my favorite Giants Teams of all time.

I'm not saying that Ross is terrible

I don’t think he’s useless, and your points illustrate why, but overall for the year, he was amongst the worst. Blame Radio, injuries, poor play, whatever…. taking the year as a whole, he had a {Bill Walton voice} TERRRRRRRRRRRRRRRRRRRRRRRRRIBLE year.

Yeah, Ross has been getting a lot of undeserved hate

OK, the guy isn’t a shut down corner, but I can’t recall many times where he got beaten deep. Everything has been underneath in the zones.

where are the "yards per catch?"

b/c that right there would show you why Webster gives up receptions….he’s coached to surrender the underneath pass in a zone heavy scheme.

of course, they don’t even address scheme either.

they make NO Mention of who the CB is assigned to, but defend Tramon b/c he has to see Megatron twice this year?!?! Cry me a friggin river.

These are just their own sporratic #‘s that probably can’t even be substantiated. All i know is that Webster was targetted a lot this season….in the top 10 but doesn’t surrender top 10 receptions or yards.

and he’s seeing the #1 pretty much all year (hence why he got the targets).

and something seems fishy about top 10 and bottom 10

why not just list them all?

i mean they did the work right? it’s already documented.

that makes sense...

i just hope that the poor bastards who do pay get to see other statistics such as Yards per Catch. TDs. PDs. and i hope they specify who’s defending who b/c it seemed odd to me that he would only take up tramon’s cause….but i guess if this is just the truncated version i understand.

Interesting

The article doesn’t explain how they level the stats for different defenses, different game conditions, etc.

So if you’re Tramon Williams and you’ve been defending leads, giving up meaningless catches and yards, you suck. If you’re Aaron Ross and you play in soft zones that invite teams to complete the passes you suck. First thing they teach you in a serious stats class is that garbage in means garbage out.

PFF where they attach numbers to opinions and masquerade them as stats.

in fairness

GB numbers wise had one of the very worst defenses all year, and it wasn’t just Williams. Note the New England had a pair of names pop up on both lists. They’re not doing too much opinion wise, if anything I’m presenting much more of an opinion here – for the most part, these numbers give a bit of credence eyeball wise to who I think had good and bad years.

What I'm saying is that they make every snap equal which isn't true on face value

They don’t adjust for scheme, they don’t adjust for opponent, and it’s well established that they don’t get a full feed

So for arguments sake lets consider a play from the last game:

The Osi strip sack. On that play Ross guesses wrong and gets burned. But the ball never comes out. So how does PFF account for that? Probably Ross’s single worst moment, from what I see PFF calls it a victory! He played a snap without getting targeted.

Now the yardage. How do they know that the guy they think is responsible for coverage is responsible. The Giants blew coverage over and over and over, so we are saying that if Ross goes into chase mode he gets the yardage. I guess that’s ok, but it’s not scientific or informed. It’s basically educated guesswork.

I like seeing the numbers, cause its some kind of data, on positions where we don’t have much, but based on the wild swings we’ve seen in some players PFF scores year to year, indicates that their methodologies aren’t as tight as they need to be.

I completely agree

As some of you may recall from the comments sections in the weekly PFF grades, I’m not a huge fan of their somewhat arbitrary number grading system that doesn’t seem to match up with what we just saw most of the time.

The interesting take from this specific link is that it kind of passes the eyeball test. Orlando Scandrick and Quentin Jammer for instance got burnt like they took gasoline baths before most games.

If stats were king the Iggies would have won the SB based on their CB's stats coming into the season,among other great traits they supposedly had LOL
