I think alot of people have some misconceptions about Tampa 2/Cover 2.
The difference is the Tampa 2 is a variation of the Cover 2 where the ILB helps cover the void that both Safeties can't cover in the middle. He's has that deep middle responsibility where the Safeties can cover their zones on their respective sides of the field. It's basically a Cover 3 concept but the ILB is playing underneath. The Tampa 2 was invented to cover for the shortcomings of a straight Cover 2 where the weakness is to split the Safeties. That's why the ILB has the deep middle responsibility.
The coverage of the corners is solely up to how the coordinator wants to play them but they do play alot of outside leverage to force the routes to the middle where the help is.
The confusion lies in what kind of technique the corners will play in. Ryan didn't use a lot of press coverage like we thought he would and Kiffin's scheme is flexible enough to play any type of technique whether it is off, press, press-bail in a zone or man call. Claiborne played an almost exclusive Cover 2 at LSU so there's really no issue with him nor should it be with Carr who excels at both zone/man.
The real problem that you should be arguing about is the changes that need to be done on the DL in order to generate pressure, turnovers, sacks, etc. On paper it seems like we have a decent group but you need depth and talent to carry you through a full season.
