This is very likely the case - and it is very sad.
The "precision modifier" is a horrible game play mechanic that continues one of the worst design decisions in Madden history: moving "sprint/acceleration" button to the right trigger.
The placement of sprint/acceleration on a/x, and the PS2 control layout in general, was far more intuitive and inherently more realistic. It forced you to "let off sprint" to perform moves requiring "footwork" - the change of direction or "quick juke" was more of a "footplant" than anything we have seen since. Yes the locomotion on PS2 left some serious desire for improvement, but zig zag running continues even within M25.
You want combo buttons - how about ones that make sense - like stiff arm left or right on triggers and holding both = cover ball. Same with strip ball left/right directional and holding both = wrap up tackle.
Everything that was put into "precision modifier" could have, and should have, been accomplished utilizing the ratings of the ball carrier, the timing of the move, and the input into the controller - just like "passing trajectories"
Take Y/Triangle for catch - tapping the button would be a "in stride" animation, pressing and quickly releasing would be a quick moderate jump animation, holding the button down and then releasing would allow a player to really gather in for high leaps - timing would impact the player's ability to not only high point the ball but also have a "trip/slip/lean" aspect to it. Failure to time the button input correctly could result in a player watching the pass sail over head, tripping or slipping, and even catches or incompletes where the receiver's leap makes the player's body lean in such a way that they fall during the animation...
You can apply this to every move, even the stick jukes and trucking/hit stick - flick the stick for quick pop animation, hold it direction for more impactful/ but also riskier animation - spins, dives, hurdles - and now you introduce the ability for "combos" that make football sense dive while holding both triggers to pull ball in close to body, dive while holding stiff-arm button to reach for first down marker/endzone. Hold strip on one side to "wrap" ball carrier while tapping with the other to attempt to "punch the ball out".
Pass rushing you hold dive and tap strip for "strip sack" animation - complete with risk of QB shrugging you off and late hits. Pass rush moves that are intuitively mapped to directional bumpers/triggers so power moves are on triggers with variations built in to how you press/tap/hold button same for finesse moves on the bumpers.
Nothing is added by "precision modifiers" that they could not have accomplished by looking back at what was one of the strengths of Madden on PS2 - the logical and intuitive controls that made sense not only for the user, but the "programmers" as well...
