The Oakland Raiders will hold a three-day voluntary veteran mini-camp next week at their Alameda, Calif., facility. Due to the coaching change, Head Coach Jack Del Rio and his staff are afforded an extra mini-camp.

The Raiders have been one of the more active teams in free agency this offseason. With net free agent gains and losses, veterans moving on to other clubs, the installation of new offensive and defensive schemes and philosophies, there are many questions to be answered between now and the start of the regular season.

Here are 10 questions heading into the Raiders veteran mini-camp next week:

1. Jack Del Rio Era: Practically an entirely new coaching staff will take the field Tuesday. What will practice look like, how will the coaches interact with the players, and who will emerge as leaders on the field and in the locker room?

2. Shuffling of Offensive Line: Stefen Wisniewski is out and Rodney Hudson is in at center. Austin Howard is moving from guard to tackle. How will Hudson fit in with his new linemates? Who will fill the role at right tackle?

3. Latavius and Company: Is Latavius Murray ready to be the bell cow? With RB Darren McFadden in Dallas and Maurice Jones-Drew retired, the Raiders will need a feature back to step up. Where does Roy Helu, Jr. fit? Can Trent Richardson return to his college form? Will Marcel Reece get more carries?

4. Playmakers (WR): What does Michael Crabtree bring to the Raiders offense? How is Rod Streater's injury comeback? How will this group mesh with QB Derek Carr and Bill Musgrave's offense?

5. Ken Norton, Jr. Effect: What is his practice energy level? Norton's practice demeanor is well-documented. It'll be interesting to see his intensity and observe his teaching methods.

6. Musgrave's Offense: We'd never give away trade secrets, but what will the tempo be, how complex will the offense be? How will it all come together with each unit working together?

7. Tight End: Is Mychal Rivera ready to make the jump to the next level and how will Lee Smith fit in?

8. New Man in the Middle (Curtis Lofton): LB Nick Roach is out and Curtis Lofton is in. His productivity speaks for itself, but what is he like calling the plays in the huddle, lining his teammates up? Does he lead by example or is he a rah-rah guy?

9. Youth Movement at DB: The oldest Raiders cornerback is 26 years old.

10. Attendance: How many players will participate in this camp?
