ALAMEDA, Calif. -- What, exactly, are the Oakland Raiders doing on defense?
More specifically, what did they do to improve the league's 26th-ranked unit, a unit that will start rookies at defensive tackle in third-rounder Eddie Vanderdoes and at middle linebacker in fifth-round pick Marquel Lee?
It might turn out that Lee is the most scrutinized Raiders defensive player on the field Sunday in Nashville as Oakland opens its season against the Tennessee Titans -- even with reigning NFL defensive player of the year Khalil Mack wearing silver and black.
