During the early part of his career with the Green Bay Packers, it was obvious to anyone watching that Javon Walker had the potential to break out. He did in 2004, but injuries slowed him in 2005 and ’07 when he was with the Denver Broncos. Still, the Raiders gave the wideout a six-year, $55 million contract in 2008. Walker made 32 receptions for 196 yards and one touchdown, and then had to be talked out of retirement by Al Davis. Walker appeared in three games in 2009 before being released.
