I guess that it's just a random coincidence that most posts that complain about man vs zone coverage reference only the CBs.
Even when we use man coverage, with Kiffin 90% of the time it is going to be a cover-2 look with two deep safeties. Same as it is when we run tampa-2. The variance for the safeties between those coverages is very minimal. Towards the end of the season when we went to more cover-3 and cover-1/cover-0, then things really changed for the safeties, but by that time the entire defense was limping.
I don't think most posters are lost on the fact the coverage effects the entire defensive backfield. I think it is simply much easier to see the cornerbacks play because our issue was predominately against the short and intermediate, which is the CB's responsibility 9 times out of 10 in the defense we ran last year.
I didn't mean to come across as crass. There has just been a real attitude of "I'm smarter than you" around here lately and your post about people not know how the defensive schemes effect different players, sort of came across that way. Im sure it wasn't your intention.
