I figure the way the Pats defence is set up is that they don't mind giving up plays between the 20's, but once the opponents are in the red zone that is when there defence kicks into action. I don't think they value corner backs too much; hence there style on defence. They figure once they are in the red zone the LB's DEs and SS will take over. I think this is also the reason why Samuel will not get the money he wants. BB feels he can put any CB in there system and it will work out. When the LB and DE are putting some much pressure on the QB it has to make life easier for the CB, which is what is going to happen this year. The Pats had the best red zone defence last year. At this stage there is no longer a deep threat. The lines of scrimmage is where you have to score the TD. "Keep you body low and your legs moving"
