Strategy card question

So, what’s the difference between Man 2 Man and the Ball Hawk card?  They both give +2 to CB’s.  Am I missing something?

They give +2 for different stats, for example idk all of them but lets says theres two strat cards for Rbs. They both give +2 stats but one gives better juke moves while the other one gives better trucking. For the CB ones i would just pick the man coverage one tho
