Janikowski has a 151/158 record on attempts from 33 or closer, I don't see the Raiders having issues.
So this off season the Raiders let their CBs test free agency, it wasn't a stellar class, but Chimdi Chekwa ended up being picked up by the Patriots. Which was good for them because they have probably the lightest dback roster in the league.
Patriots just cut Chekwa, who resigned for Oakland. I'm not exactly sure who you guys have back there now, but it's not looking healthy for the Patriots D.
