We have been waiting for the time that Cardinals cornerback Patrick Peterson would become a shutdown corner against top flight receivers. But has that time already come?
Without seeing any type of stats, we know that Cardinals cornerback Patrick Peterson has been fantastic this season. He has shutdown the best of receivers that he has gone up against, allowing very few catches. If he does allow one, it usually doesn't go for many yards due to Peterson's tremendous speed and tackling ability.
But just how good has he actually been?
Pro Football Focus released a statistic on Twitter yesterday stating that Peterson has allowed just 0.38 yards per snap in coverage. That comes out to the lowest number of any cornerback with at least 100 coverage snaps taken. The longest pass completed to a player Peterson was covering was 16 yards. That is saying a lot considering he has been forced to match up against Sidney Rice, Brandon Lloyd and DeSean Jackson.
I took another, more in-depth look, at Peterson's stats on PFF and saw that he has only been targeted 16 times through the first three games of the season. In that span, he has allowed five receptions.
Peterson is 83rd on the list of the top 100 corners in average yards allowed per catch. The best? Darrelle Revis of the Jets, who is out for the season with a torn ACL. However, Revis is 85th in terms of snaps taken, whereas Peterson is tied for fourth with 229. With him being on the field much more, he is bound to give up more catches, increasing the chance that they go for big plays (which they haven't).
So how close is Peterson to becoming the shutdown player that the Cardinals hoped they were drafting fifth overall from LSU? In my opinion, I'd say he is already there.
