Numbers game shifts Woodson to safety -- again

Posted by ESPN.com's Kevin Seifert
A personnel glitch will leave one of the NFL's top cornerbacks playing safety for the second consecutive game.

Charles Woodson will start at safety against Houston on Sunday, Green Bay coach Mike McCarthy told reporters Wednesday. Woodson will replace the injured Atari Bigby (shoulder) and start ahead of backup Aaron Rouse, who has been dealing with an ankle injury but returned to practice Wednesday.

Nickel back Tramon Williams will start at Woodson's cornerback spot, joining a starting secondary that also includes cornerback Al Harris and safety Nick Collins. The Packers consider that quartet their best four defensive backs, and value their collective presence more than maintaining position integrity.

I can see where the Packers are coming from on this move. I'd rather have Williams starting at cornerback than Rouse starting at safety. But given how hard it is to find top-flight cover corners, it's unfortunate that Woodson has to move out of his best position to compensate for the Packers' lack of depth at another.
