Best CB's to get? Peterson,Revis,Moss?

Or anyone else? My cb's right now are Deion,Boldin,Sauce and DK. I like DK cause he gets 0ap flat zone KO and he's my #4 and also he plays in my 4-6 speed package. I'm thinking Peterson cause he gets 1ap OSA which I can pair with Boldin who gets it for 0ap. I run mainly ZCV with some MCV thrown in but ive been thinking about running more MCV and if I get Peterson then that's two OSA for 1ap and I also have Davante BB MLB card that gets 0ap inside shade. Price really isnt a problem as I have 9+m coins and run a 49ers TT but with the strat cards theme teams arent that important. I know Revis gets inside shade for 1ap so I've thought about getting him but Peterson's 1ap OSA looks nice. Moss looks good but its all about abilities in this game but I do love his run stopping attributes.
