Thanks. That was the first time I tried it. Since it never really worked on previous games I was hesitant to try at first. One day I just said screw it and gave it a whirl.
It doesn't always work, but I think the percentage of success is pretty close to real life.
It really does make a difference if you have big receivers. I've tried to throw up a few to Kenny Stills and Brandin Cooks with much, much less success.
It works well with big receivers but I wouldn't attempt it outside the 5 yard line.
Here's one I did to Jimmy Graham last night. It wasn't as pretty because he blew past the coverage pretty easy. Some look better than others Sorry for the shaky cam.
