How would a 3-4 zone blitz defense be set up

What would be the attributes and important things to know about each position

DT - Like any 3-4 you'll probably want a big body who can help stuff the run or rush the pass rusher. Someone like gravedigger would probably be ideal

DEs - not super important but these players need to be able to do a mix of stuffing the run and rushing the passer

OLBs - Since you want to run a zone blitz it's important that these players be good pass rushers look for high finesse or power moves on these players. It's pretty rare but occasionally EA will release that have the stats to rush the passer or drop into coverage. You may want to invest in players who can do both since it gives you more options to defend your opponent

MLBs - should be fast and have good coverage. Being able to rush the passer is also a plus

CBs and Safeties - The usual ratings likezone, awareness, play rec, speed. Maybe man if you want to use any match
