The Browns can't tackle. This might well be the play that cost Cleveland Browns safety Jermaine Whitehead his job. Broadcaster Dustin Fox called Whitehead's tackling Sunday against the Denver Broncos a joke. Whitehead responded with a series of threatening and racist tweets and was cut by the team Monday morning. The Browns called his outburst unacceptable and inappropriate. As was his tackling Sunday. The Browns season continues to unravel.
