Answer
Hi
  The cover 2 is a tough defense, it takes a lot of mental and physical skill, you need to think on your feet and be ready to read the other player very fast.
You need to drill on this allot if your going to use it effectively, and your players have to understand how important their job is at each position.
With that said ESPN has an area College football 101. It has all the info I would tell you here but has diagrams that will probably help you more than I can by telling and not showing.   http://espn.go.com/ncf/columns/davie/1437187.html
