It seems like every year there's some story about how slow it's going with rookie contract negotiations, and every year it seems to work out fine. NT B.J. Raji signed after missing the first two weeks of training camp, but he didn't get off to a slow start in 2009 due to the missed practice time: it was his ankle injury that limited him.
Here's the list of 2010 draft signings from Walter Football.
The good news is that S Morgan Burnett appears to be the next Packer draft choice to sign. If there is any player who needs all the practice time he can get in training camp, it's Burnett since SS Atari Bigby remains unsigned. I expected Burnett would be the next Packer to sign two weeks ago, but TE Andrew Quarless jumped ahead of him as the Packers continue to sign their way backwards through their draft choices.
