The Oakland Raiders agreed to a one-year, $1.8 million contract with former cornerback Charles Woodson. Including incentives, the deal is worth a maximum of $4.3 million according to RotoWorld.com.

Division rival, Denver Broncos, also offered Woodson a one-year deal, but worth $3.7 million through reachable incentives according to the Denver Post. Oakland’s agreement includes incentives described as ‘hard to achieve.’

It seems somewhat surprising Woodson chose Oakland over Denver with the Broncos a clear Super Bowl contender this coming season. The fact that both contracts are based on incentives makes the decision even more puzzling. But as the saying goes, what’s the difference between $4.3 million and $3.7 million: $600,000. That total may be chump change for the NFL, but it could be a significant amount for a 36-year-old football player.

Of course, Woodson did spend his first eight seasons with Oakland who drafted the defensive back fourth overall in the 1998 draft. Woodson was a member of the last Raider team to make the playoffs in 2002, and in 2001, forced a fumble against Tom Brady and the Patriots in the AFC Division Round only to see the call reversed because of the “Tuck Rule”.

Woodson joined the Green Bay Packers in 2006 winning the defensive player of the year award in 2009. The Pro Bowler became a Super Bowl champion the next season.

The defensive back has certainly lost several steps since then, but the Raiders believe Woodson is the best option to play next to other safety Tyvon Branch. Oakland expects Woodson to play somewhere between 500 and 750 snaps this season according to RotoWorld.com
