The top seven are set, are healthy, and give us major improvements over 2011. All are ready to play. They will likely get 99% of the defensive reps, even with an injury or two. We don't seem likely to carry any developmental defensive backs on the 53. WHAT ARE THE FUNCTIONS OF THE REST OF THE DEFENSIVE BACKS? IMHO, All would need to be expected to be active as Special Teams players. One strong safety and one corner seems best, giving us 5 corners and 4 safeties. WHO ARE YOUR CHOICES? CORNER? SAFETY?
