Use curls, they’re just like comebacks but way quicker, now idk your wrs but I have lemon who has taken probably 25 curls to the house off of mid blitz. Most likely they won’t press you and if they do someone is bound to get open deep as long as you block the rb or te. Another thing to look for is the te if you don’t block him because they are just naturally op especially if it’s a formation where he is on the line of scrimmage. Out routes kill the safeties on mid blitz because they aren’t able to press. For example trips te is a good formation for mid blitz because the te has the whole side to work with and if the guy starts to adjust to that then you switch it up and make him post or drag.
I usually go into Trips TE whenever I face mid blitz. I'll block my TE, put my RB on a stemmed up post or texas route, outside WR on a slant or drag, and then I'll either put my slot WR or inside WR on a stemmed up speed out route and the other WR on a post. My first read is always the speed out and if that's bagged I'll go slant/drag, then RB and last post. If it's fourth down I'll sometimes shift my running back over and block him too or if it's an early down I'll move him outside. Texas routes with an RB lined up at receiver fry man usually. After you hit the speed out a few times most people will get out of mid blitz. I'm in campus legend and I've rarely seen anybody be able to stop it.
If they’re pressed or inside shade, speed outs.
If they’re outside shaded in routes stemmed however high u want.
Comebacks if they’re off coverage. If they click on while pressed underneath, they can play it.
Obviously go routes against press as well, but you’re guy has to have good speed and release to break away.
Mesh also works too.
