Obviously the two biggest holes on the defensive side of the ball are at the safety position and the linebacker position. I'd expect the Jaguars to target the likes of Eric Weddle, Quintin Mikell, or even Atari Bigby at the safety position.
Alfie Crow emailed me about Bigby, and here's what I had to say about him:
I mentioned Smith because he played for the Packers and Jaguars last season.
With the return of Burnett, and the starting job currently in the hands of SS Charlie Peprah, it doesn't seem like the Packers will go to any great lengths to keep Bigby next season. I wouldn't be surprised if some team views him as a low cost option to start in 2011, and offers him a two-year, $4 million contract as a free agent. But with his history of injuries, that might not be available to him.
There's no chance they'll overpay him because he's not going to open the season as the starter. Assuming the free agent market is soft, do you want the Packers to bring him back next season?
