Weekly Patriots mail is delivered

Every Tuesday on ESPNBoston.com, questions from Patriots followers are answered as part of a weekly mailbag. This week's mailbag has been posted and includes some of the following topics:

1. How the lockout is tied to Bill Belichick's experimentation on defense.

2. Putting all defensive linemen into one of three categories -- "locks", "middle ground", "longshots".

3. Revisiting 2009 second-round pick Ron Brace and his future with the club.

4. Looking deeper on the receiver depth chart and focusing on Julian Edelman, Brandon Tate and Taylor Price.

5. Considering an in-house option at safety if the Patriots are looking for improvements.
