FIVE QUESTIONS ENTERING TRAINING CAMP

1: Is Carson Palmer still a premier NFL quarterback? He will have an entire training camp this time, but he also will have a new offensive system that will demand versatility.

2: Can Darren McFadden remain healthy? McFadden appeared to be en route to a 1,500-yard rushing season until a midfoot sprain. He has never played more than 13 games in a season.

3: How will new coach Dennis Allen hold players accountable? Allen is promising accountability for a team prone to penalties and mental mistakes. He will set the tone in camp.

4:What happens with Rolando McClain? The new regime likes what it has seen in terms of dedication and work ethic of the disappointing middle linebacker. But there is a six-month jail sentence under appeal.

5: What receiver steps up to join Darrius Heyward-Bey? Last year's rookie flash Denarius Moore heads the list, but keep an eye on Jacoby Ford and fifth-round pick Juron Criner.
