The starting cornerback opposite of Tramaine Brock remains a mystery for the San Francisco 49ers.
The club rotated several defensive backs in the preseason. The process illustrated just how much depth is at the position.
Free-agent addition Shareece Wright along with 2014 draft picks – Kenneth Acker, Dontae Johnson and Keith Reaser – all saw first-team reps in training camp practices and preseason games.
The fluid nature of the competition appears to bode well for Eric Mangini's defense. San Francisco has several options for base and sub packages when they choose to announce their final choices prior to a Week 1 home matchup against the Minnesota Vikings.
