A great pass-rush isn't just reliant on talent at the linebacker position, but also the ability of the secondary to take as many options away from a quarterback as possible. For that reason, talent at the cornerback position is a must.
Jimbo Fisher's 2012 signings included two corners with Ronald Darby, who was on the ESPN150 list, and Colin Blake, a 3-star signee out of San Antonio. The Seminoles also picked up a ton of other defensive standouts to build future depth with an already nasty defense.
The 2013 class so far has two players for the Noles' secondary and certainly seems capable of becoming the next set of shutdown corners.
