CB Jarrett Bush is a restricted free agent, but the Packers tendered him the lowest contract they could and still have the right to match any offer. So they would receive nothing if they don't match the offer sheet he signed with the Tennessee Titans.
Bush was picked up in early 2006 after he was released by Carolina. He played little that first season, but was the nickel cornerback all of 2007. He was fine most of the time, but he also got torched in a couple games. He was pretty badly abused by WR Sidney Rice in the 2007 game at Minnesota. He entered 2008 in a battle with CB Tramon Williams for the nickel job, and he lost. Williams played much, much better in 2008 than Bush did in 2007. By the end of training camp, Bush was receiving reps at safety. He didn't play cornerback at all in 2008. Although he had 17 tackles on special teams, and downed more than one punt inside the 5 yard line, he also committed a few penalties on special teams. He can play, but the Packers can do better.
The combination of receiving a low tender and the signing of free agent S Anthony Smith probably means GM Ted Thompson had no intention of matching any contract offered to Bush. As much as I would miss one of the few Packers with an blog, his loss would have little impact on the team. They might even be better now with Smith. Titans' fans are looking forward to having him on the team, and they'll get their wish because the Packers are probably going to let him go.
