He has close to a $3M cap hit this season, is now on the wrong side of 30 and is still suspended for the season's first four games.
Ultimately, he was beat out by Maxwell. You can't really justify wasting $3M in cap on a bench player. That money basically paid for Kevin Williams and a Doug Baldwin extension.
The big loss was not re-signing Thurmond (who can start at nickel AND return punts), not Browner (I love me some BB though).
