I could see it end up being something like Trigger+Receiver Icon+Thumbstick with different directions correlating to different "targets" (i.e. High and away, low and behind, low and in front, etc.) and having the triggers be tied to either a touch or bullet pass. Basically a mechanic very similar to the ball-carrier moves implemented last year and similar, but expanded, version to what I believe is already in place. The description stating that you're no longer throw at receivers and you can throw it anywhere on the field obviously contradicts that kind of mechanic though. But it's hard for me to envision them implementing any kind of difficult mechanic or something with a steep learning curve, especially if it's the default for online. Hard to say though, definitely the most interested in seeing this in action.
