Toughest position to play: corner or safety?

[Harlan Huckleby]

The old canard is that cornerback is the toughest position to play after QB. Got to be incredibly ahtletic to play man-on-man with receivers. Why, even white guy can play safety, they are just slower, less gifted corners.

Packers have had miserable time finding safeties:

Seems like we get an endless stream of playable corners. Now we are moving Hyde to safety because he can walk and chew gum and tackle.
