Let's look at the newcomers on defense for now... Morlon Greenwood - High dollar free agent that has gone 2 out of 3 games without recording a single tackle or assist. Has not been the playmaker that was advertised. Phillip Buchanon - Hasn't given up any big plays and has not made any big plays. Looked terrible returning punts. Lewis Sanders - Virtually invisible unless he's making mistakes. Travis Johnson - More penalties than tackles this preseason. The best free agent on the defensive side of the ball has been Frank Chamberlin and this guy probably won't even make the team.
