Green Bay Packers quarterback Aaron Rodgers drops back to pass during the first half of an NFL football game against the Oakland Raiders Sunday, Dec. 11, 2011, in Green Bay, Wis.

KANSAS CITY, Mo. — The play has become a staple of Green Bay Packers highlight reels. Aaron Rodgers drops back, lofts a pass down the sideline and one of his talented receivers turns around at precisely the right time and hauls it in around the unsuspecting cornerback.

The back-shoulder fade may be the most difficult play to defend in the pass-happy NFL.

Green Bay does it better than anybody.

The Kansas City Chiefs acknowledge the difficulty in stopping it, and they say they're going to do everything possible to at least slow it down on Sunday. That could mean exotic blitzes and physical play at cornerback — whatever it takes to slow down Rodgers' pinpoint accuracy.

Says defensive back Travis Daniels: "They kind of perfected that pretty good."
