It's a small move but the Packers resigned free agent LB Tracy White. He didn't show much last preseason when given a chance to play on defense, but he's a good special teams player and, I believe, he led the team in special teams tackles the last two seasons. Losing him wouldn't make the special teams any better, so keeping him is a good idea. Especially for the low price of a $250,000 signing bonus.
Despite the meager bonus amount, two other teams (Denver and Pittsburgh) were seriously interested in him which goes to show that he really has some value.
