At first I wasn't very impressed with GM Ted Thompson's draft day trades. They seemed to be moving down in one round to move up in a later round. But the moves did net them one extra draft pick, so they've come away with 10 players. And since he felt it was a deep draft in the later rounds, that extra pick should help the team. From the Journal-Sentinel:

"We feel like we were able to get good players deep," he said. "I don't know if it was different than other years, but we felt pretty good with the guys we were able to get. It looked that way, which is the reason why we moved around a little bit."

He didn't appear to specifically state he wanted extra picks for this reason, but he doesn't like it that he can't sign undrafted free agents. The Packers signed two players after that the draft, LB Frank Zombo and CB Sam Shields, that were significant contributors on defense in 2010. From the Journal-Sentnel:

"It’s very disconcerting for a person like me," said Thompson. "I like to have a piece of paper in front of me that says, ‘These are the rules, now go get ’em, compete just like anybody else.’ It’s confusing and it’s exacerbating and it is what it is."
