Chad Jackson looked like he might be a steal when he was drafted 36th overall by the New England Patriots in 2006. He had run a 40-yard dash time of 4.32 seconds at the combine workouts before the draft. That was the fastest among all receivers that year. He had good size, at 6-foot-1, 215 pounds. The Pats traded up 16 spots in the second-round in a deal with Green Bay to get him.
But Jackson battled through injuries and had just 13 catches as a rookie. He tore an ACL in the AFC title game at the end of the '06 season. That hindered him in 2007. He started out on the physically unable to perform list and didn't get activated until November. He appeared in only two games.
In 2008, Jackson was in a battle for the third receiver job (behind Randy Moss and Wes Welker) and was beaten out by Jabbar Gaffney. He hooked on with Denver late in 2008 but was cut by the Broncos before the start of last season. He sat out all of 2009.
The Bills are a team in need of help at receiver, with just four other veteran players at the position. They have nothing to lose in Jackson.
