Former Tampa Bay Buccaneers defensive back Ronde Barber believes that cornerback Darrelle Revis is not 100% healthy at the moment.

Revis sustained a torn ACL in the 2012 season while playing for the New York Jets that required surgery, but despite featuring in every game this campaign, Barber feels that something is wrong with the All-Pro.

"I don't think that knee is back to where it was yet, but he still has been playing well," Barber told The Tampa Tribune. "Probably not where he wants, but it's not like he's a liability."

The Buccaneers are yet to win a game this season and are 0-5 going into week seven.
