Those variety of combinations as you mentioned meant squat in 2009...or have you forgotten how much of our leads in the 4th quarter melted away last season?.
The players at safety all have skill but there have been breakdowns last season in the last quarters and the Safeties while they were better than the corners at times,had problems keeping leads late and opposing receivers from doing damage as much as any other part of our defense,we simply could not shut down teams that were behind at the end of the 3rd quarter,especially teams with good quarterbacks...that MUST be fixed this year.
4th quarter breakdowns have to be a big issue of fixing with BB and his boys,both safeties and corners....of course a pass rush would be nice as well to help them out.
