Weekly Patriots mail is delivered

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

1. Closer look at the safety spot and its level of need.

2. Some of the prospects in this year's draft at safety and why it isn't considered by some as a deep class.

3. Special teams considerations and players who solely factor into that third phase of the game.

4. Why Ohio State linebacker Ryan Shazier ranks as one of my favorite prospects in the draft.

5. Concern over the depth along the defensive line.

6. Quarterback Ryan Mallett and the possibility of his return in 2015.
