I really don't think Samuel is worth 10-11 per year. He is a product of the Pats system and IMO he will not be as hungry to win the Super Bowl with a fat paycheck and his past success with the Pats. We need to spend that money elsewhere.
I don't think Peyton Manning or Tom Brady or any one player is worth that much personally, but you have to pay to play. You can't call Samuel a system CB becuase the Patriots don't really have a system. Their defense is so diverse, and changes so much from week to week, that they almost run a completely different defense every week. The only point I will say that coincides with your thought is that Samuels stregnths are more suited as a zone CB, and we run more of a man to man system.
