Correct me if I am wrong but this is how i see the Tampa 2
The primary difference between the base 4-3 D and the tampa 2 is found at the middle linebacker position (MIKE) where they are not only responsible for run support but are also prone to drop back in pass coverage, sometimes deep coverage normally reserved for a safety.
The secondary isn't a complicated scheme. It's a "cover 2″ shell with the safeties covering "over the top" of corner backs.
The "cover 2″ essentially has the safeties dividing the field in half with each covering their respective side. The "Tampa 2," when the MIKE position drops into coverage, essentially changes the coverage to a "Cover 3," or the backfield divided into thirds versus halves.
The premium ingredient is having the right personnel in place. A MIKE that can handle both run support and effectively cover the defensive backfield with as much speed and talent as a safety isn't as simple as it may seem.
That's an excellent description. There are minor differences w/ the DTs, with one of the two DTs being freed up for more one-on-one opportunities (the Sapp role when he lined up w/ Booger McFarland).
My thinking is that there are lots more fast undersized LBs on the college level than, say, big oversized LBs that you'd need for something like the 3-4. Plus, it should also be easier to integrate young CBs, because it's more about "attitude" & preparation than pure speed in this system. Plus, Kiffin is the MASTER. I couldn't imagine anyone -- especially someone worried that they might never bulk up to a 250 pound LB -- not wanting to be play for Kiffin!
