In my opinion man coverage abilities are pointless on PS4.
I have used all of the shades, OSA, and all of the Route KO’s. It has been EXTREMELY rare for me to see any of these abilities light up.
I have also used a lot of the top CB’s in the game with the abilities listed above so it’s not like my CB’s are just too slow or not agile enough.
If you play on PS4 I would recommend spending your AP on Acro and Zone abilities instead of Man. Then just mix up your scheme between Man and Zone.
Good Man corners can still cover really well in Man without abilities and if you are close to the WR and you press ”square” they can still get knockouts.
Unfortunately certain formations/routes are going to beat any corner in this game no matter what abilities they have on them.
If somebody is on PS4 and seeing these abilities work how they are supposed to, feel free to comment and let me know what I’m doing wrong.
