A towering presence on the field, Walker - a former first-round pick - topped 1,000 yards in his last two healthy seasons. With 30 touchdowns over his last three healthy seasons, Walker is a formidable red-zone presence.
Staying on the field, however, has been a problem for the talented 6-foot-3 wideout. He missed eight games in 2007 and played in just one contest in 2005 for Green Bay.
If he can stay between the hash marks, Walker provides the Raiders with a legitimate number one receiver that will allow JaMarcus Russell with an outlet, aiding his growth.
The deal is reportedly worth $55 million with $16 million guaranteed.
