Re: Kareem Jackson's plight.
On a different play, there was a 5-yd holding call (away from the play) that was declined since the Chargers gained 10 on a pass to Sproles.
Namdi committed the penalty because he had allowed the receiver to cut back to the outside.
Then came a play in which Namdi funneled the receiver inside toward the single safety, but then allowed the receiver to cut back to the outside over the top.
(This is why CB had to honor the outside route.)
Fortunately, the pass was off-target (the pocket collapsed and Rivers couldnt step into the throw.)
I'm not going to show those sceen shots, but those plays clearly showed that as CB, you have to honor the corner route (or any type of outside route) as you funnel the receiver to the inside.
If you let the receiver cut back to the outside, the safety won't be able to help.
