This is what I wanted to touch on right here. I remember in the webcast describing the different trajectories they said they had changed the button mechanic so it was about how long you held it instead how hard you pressed it. I loved hearing that because I had felt for a while that was the best way to clearly have a distinction between bullet, touch and lob. However, in the demo, the ball still seems to be thrown as soon as I press the button, not when I release the button as described. Now I haven't practiced this extensively enough to say it's not working as described, that's just how it seems in the few times I have played the demo.
As far as "super linebackers" I know there is a whole thread discussing if there was ever such a thing in regard to them jumping and that it was the pass trajectories, not the LBs jumping that was the issue However, the discussion also broke down that the "super" was referring to the reaction times and LBS going from moving one way, right into INT animations another way, without any transitional animations in-between. I think the OP of course makes a good point because without addressing player movement, which includes those transitional animations, it seems rather obvious all players can still perform "super" feats in Madden.
I saw a few instances last night of LBs making INTs in the middle of the field for passes meant to go deeper down field. I was concerned about the fact of an instant INT because I felt those should have been tips or attempted INTs, instead plucked right out of the sky. I can completely understand how someone would tie that into "super" reaction time because the LBs gathering themselves to jump up to make such a flawless INT does look rather unrealistic at times.
That said, I do think there was a lot of human error on my part for the type of passes I threw in those instances too. My point is I don't feel the INTs played out realistic by the LBs do to the way they still move and can instantly access INT animations with seemingly no realistic transition. Yet I also understand that there are things a could have done with the passing mechanics to avoid them getting their hands on the ball in the first place.
In a nutshell I think the OP is right about "super" LBs because all players in Madden can still move and react in completely unrealistic ways. However, the I believe most INTs and pass deflections by LBs due to those issues can be avoided by better utilizing the current passing mechanics.
