Safety is the RB of the defense. You can plug almost anyone into this scheme and they will be OK.
People need to stop worrying about Defense. McD can scheme up enough answers during the regular season.
During the playoffs it doesn't matter anyway no matter how good they are, the offense is going to need to carry them because they can't stop anyone when it counts.
Load up on offense and do enough on D to get by.
The definition of insanity is doing the same things over and over again that haven't worked and expecting different results.
The focus needs to be on offense, forget the defense. Fill it in like they did with the offense last year.
Also, plenty of viable safeties will be around in the 5th and 6th rounds. You don't waste high picks on non difference making positions.
