For my latest post at The League, I wrote about five free agents that could help any team in any system. As an example of one player who can't play for any team, Panthers DE Charles Johnson is great, but he'd be underutilized with the Green Bay Packers because his best position is as a defensive end in a 4-3 defense. From Washington Post.com:
This isn’t meant to be a list of the best free agents, but instead it’s a list of five free agents that any team could use. The NFL is a passing league, and flexible players who can help in the passing game on offense or defense are more valuable. These aren’t all the players available who can fill these roles, but they are a few players I would consider if I was running any team. It would be understandable if any team pursued these players even if in reality it’s unlikely to happen.
I mentioned DE Cullen Jenkins because his inside pass rush would be a welcome addition to any defense. While I don't expect the Packers to do anything in free agency other than re-sign their own free agents, Browns DE/OLB Matt Roth is an interesting name as someone who can play on the strong side and allow LB Clay Matthews to move back to the weak side.
