When you sign 6 new starters and have second year player that is going to start, just how many do you think you are going to add in the draft (Carter, Carr, Pool, Bernadeau, Livings, Vickers)? Plus Carter makes it 7 new starters.
Then he uses Polamalu as an example of someone who started off on ST's and backup role that became a starter. Crawfor, Wilbur, MJ? Could they develop into starters down the road?
