Asante has been torched this year Pudge. I'd go back and cite the various times that he's been beat by 10 yards, but I have to get back to work. It has been more than once or twice.
Yes, Asante has given up some notable big plays this year, but you are exaggerating if you think Samuel is playing poorly. He has been playing very well. And outside 3 or 4 big plays he's given up, there really is no reason to complain about his play. As was discussed in the Grimes thread, corners get beat from time to time. It goes with the territory.
Let's cite the examples of big plays Asante has given up.
He got beat by Vincent Jackson vs. TB. Got beat on a deep pass. Made a bad play on the ball, which can happen. He also got "torched" by Teddy Williams vs. Arizona. I can't remember which of those plays, but one of them was because he didn't have safety help from William Moore. So he's not exclusively at fault.
Then he gave up a 30-yard catch to Brandon LaFell vs. Carolina. That play was directly the result of Asante being Asante and trying to bait Newton and jump the throw. Unfortunately, Newton didn't take the bait and threw the ball over Asante to LaFell. But I put zero fault on Asante for that play because it came when there was 10 minutes left in the game when the Falcons were down 7 and Asante was trying to make a play. Then he did make said play when he stripped LaFell from behind. If Alford had recovered it, and the Falcons capitalized and marched down the field to tie the game, you'd be talking about Asante made the play of the game.
Let's be scientific about this, looking at the stats through Week 9:
Asante has blown 2.5 coverages thus far this year. Compare that to the other corners: Trufant (10), McClain (10), and Alford (7). As you may recall, a blown coverage is when a corner gets beat on a 3rd/4th down and it results in a new set of downs, or gives up a 20+ yard play or touchdown.
Percentage Blown Coverages per Cover Snaps:
Asante - 1.4% (2.5 blown coverages, 178 cover snaps)
Trufant - 3.3% (10, 302)
Alford - 3.9% (7, 179)
McClain - 5.1% (10, 196)
Let's compare that to last year's corners:
McClain 2012 - 2.2% (8.5, 395)
Asante 2012 - 2.8% (14, 488)
Robinson - 3.5% (20, 562)
Also let's look at how often they break up passes when they are targeted in both 2012 and 2013:
1. Asante 2012 - 26% (20 PD, 77 targets)
2. Alford - 21% (6, 28)
3. Asante 2013 - 18% (4, 22)
4. Trufant - 16% (8, 49)
5. McClain 2012 - 13% (9, 67)
6. Robinson - 8% (8, 97)
7. McClain 2013 - 6% (2, 33)
Also part of coverage is preventing completions. So let's look at how many times they are in coverage and go without a completion:
1. Asante 2013 - 12.7 snaps per completion allowed (14 completions, 178 snaps)
2. Asante 2012 - 11.9 (41, 488)
3. Alford - 11.2 (16, 179)
4. Trufant - 11.2 (27, 302)
5. McClain 2012 - 9.2 (43, 395)
6. Robinson - 8.8 (64, 562)
7. McClain 2013 - 7.8 (25, 196)
