Recently the Chargers signed WR James Jones to replace, at least temporarily, Stevie Johnson as the team's 3rd WR. Jones has occupied virtually every slot on the depth chart since being drafted in the 3rd round in 2007, by Green Bay. Because of this, and the fact that he will likely be at most "target 4" (behind Allen, Benjamin, & Gates - not even counting Woodhead), I think examining efficiency/rate metrics would best allow us to project what kind of production Jones will bring to the team.
First off, what do we get out of Jones as an athlete - or rather, what did he bring when he entered the league?
