Charles Woodson likes being back in Oakland, to be sure. But be careful about making his decision solely a sentimental one. Woodson, the 36-year-old safety coming off an injury-plagued season in Green Bay, signed a one-year, $1.8 million deal with Oakland last week that included a $700,000 signing bonus. And it's the bonus that was the major difference between the offers he got from Oakland and Denver, Woodson said. "It was all about getting something to sign,'' Woodson told SI.com. "That was it.'' Woodson said the emotion of returning to Oakland was a factor as well. Source: SI.com
