CBs are always one of the higher paid FA positions. Especially if you want a true shutdown CB. If you need a starting CB it is cheaper to find one in the draft than it is on the FA market. So moneyball says draft your CB early and pick up your interior OL/safety starters in FA where they are cheaper than finding a starting CB and/or find them in the 2nd and 3rd rnd of the draft where value can be found. So Moneyball says Levitre and Moore in FA and then draft Milliner in the 1st and pick up DT/OL in the 2nd and 3rd. Gives 5 new starters and in the long run saves the most money.
