The 49ers signed Perrish Cox this offseason to be the No.4 cornerback. He plays when offenses use four-wide-receiver formations – Tarell Brown and Chris Culliver cover the outside receivers, Carlos Rogers covers one slot receiver and Cox covers the other one.
So far this season, Cox has played 117 snaps, he’s been targeted on 12 passes and he’s given up 11 catches for 133 yards according to Pro Football Focus. He’s also missed three tackles. Cardinals QB John Skelton was 4-for-4 throwing into Cox’s coverage last week.
Through the first eight games, Cox has been a complete liability for the defense when he’s on the field. Luckily for the 49ers, he hasn’t been on the field much. He’s only played about one-fifth of the defensive snaps because opposing offenses haven’t used four-wide-receiver formations often against the 49ers. Expect that to change as the season goes on.
MIDTERM GRADE: F.

Grant,
Thanks for the interesting stat. Didn’t realize that so many of passes targeted at Cox’s receiver were successfully completed. It seems like he’s still adjusting to the defensive schemes.
On a different note, Gore, Lee and Davis (Anthony, not Vernon) made Peter King’s mid-season all-Pro team.

King also had a lot of praise for Smith and Moss in his MMQB column yesterday.

Thanks very much for the link, Mood. His comments about Smith left me scratching my head…”But I didn’t want the week to get away from us without extolling his virtues after his performance last Monday. His numbers were alarmingly good: 18 of 19 for 232 yards, with three touchdowns and no interceptions — and the one incompletion was a clear drop by Delanie Walker.
There was something else notable about his game: Not one of his 19 throws (20, actually, if you count one that was negated by penalty) was off-target. His accuracy, in a word, was stunning.”
Stunning? Can this possibly be the same guy that several of our regulars here think is the worst QB since Ryan Leaf? JaMarcus Russell?
Thanks for the moment of perspective, Mood.
You’re welcome.
Iupati and Goodwin make the Yahoo all-Underrated list. Alex Smith almost made it: http://goo.gl/DLdhk
“Though he threw short much of the night, he did have completions that traveled 10, 11, 15, 20 and 22 yards past the line of scrimmage”

There were more than one blogger who insisted that AS didnt complete a single pass beyond 10-15 yards. I wonder if they realize how wrong they were?
They do, but they won’t care.

I think Cox made of couple of ST TD saving TD’s this year.
And an F-? Being a little harsh aren’t you? You keep discussing the passes thrown to and completion % as if that were the determining factor in grading a CB. Well, how often is he on the field and the QB doesn’t go his way? That is much more important than passes thrown at/completed. If it is 10% of the time, that means 90% of the time our #4 DB is out there the QB isn’t throwing it his way. That is a good thing. That means 90% of the time he’s doing his job.
By reason alone, a QB doesn’t generally throw towards CB if the WR is covered. And covering WR’s is the main duty of the CB. Not to get throw too and have the pass fall incomplete.
An F is too harsh.
Maybe he’s grading on the curve……somebody’s gotta get the ‘F’!
