I don't care what anyone says, defense is literally useless this year. I'm ready to sell every defensive player i have and go with the fastest guys regardless of coverage stats, they mean absolutely nothing. Every single game is a shootout and there is almost no way to get stops unless your opponent makes a mistake or you get a lucky pick or a good user. Man coverage is dog shit too, well it is whenever i do it. I'm enjoying the game but man, the defense is really horrendous and discouraging.
I honestly don't know if there is a point in investing in any defensive players other than their speed rating. Just go with the fastest guys so they can put themselves in a position to at least try to make a play and that's pretty much it.
