Raiders release Badger, Johnstone

From Scout:

The Oakland Raiders released defensive end Lance Johnstone and offensive lineman Brad Badger on Friday. They also signed defensive back Kris Richard and defensive tackle Josh Shaw.

I know neither one produced as much as the Raiders would have liked, but does this surprise anybody like me? Particuarly Badger, who had been a serviceable backup for a long, long time. Well, I guess Kiffin is making the team his own. Which could be good, but who knows for sure? I think we are all prone to inordinate amounts of optimism for the product we have seen on the field for so many years, but that's just me right now.
