1. Overcoming injuries on defense and more on potential Jerod Mayo replacements Jamie Collins and Dane Fletcher.

2. Running back Stevan Ridley running with a purpose.

3. Linebacker Brandon Spikes as a key member of the Vince Wilfork-less run defense.

4. Tight end Rob Gronkowski and all-over-the-map stories about his recovery and potential return.

5. Concern with running backs in blitz pickup.
