From Barrows new article:
The question is why the 49ers tapped Cox, who only had been signed six days earlier, instead of Wright, who had been with the 49ers longer. Wright did not play on defense; even in the dime packages, it was safety C.J. Spillman,
not Wright, who entered the game.
One theory is that Cox is a bigger, more robust player than Wright and is a good tackler. If the Packers were going to run the ball with big, powerful Eddie Lacy when the 49ers were in the nickel formation -- which they did 21 times -- the 49ers may have thought they were better served having Cox in the game.
Another consideration may have been injury. Wright tweaked his hamstring and that Green Bay's frigid cold is terrible for muscle pulls. The forecast for Charlotte, N.C. Sunday calls for 64-degree temperatures with a 20 percent chance of rain. The 49ers certainly won't be in their nickel packages as much Sunday. But the warmer temperatures might mean that Carlos Rodgers, who also is dealing with a hamstring strain, could play.
