What is the best defense to get pressure?

Obviously mid blitz has been good in the past, but in my currently online dynasty the users are good and recognize this quickly and block it up/run routes to get open. I’m playing in the Natty but my buddy has 4 99 speed players on offense, a RB and 3 WRs (it’s insane, but he has recruited super well). He runs a lot of empty or shotgun where everyone will be out on a route so just a 5 man protection. I can’t just let him sit back there bc it won’t end well, what are your favorite blitzes to get pressure and bonus how do you set it up so it doesn’t look like you’re sending pressure?
