Then they need to invent it, or find some genius to invent it for them!!!
I think there is something wrong with player strides, I am not the first to mention that,
WR/DB issue need serious improvement,
OL/DL needs serious improvement (including the outside rusher arc that LBzrule posted about),
LB zone drops need some tweaks,
WRs should not just stand perfectly still at the end of their route (and I know about the way to make them move, but I should not have to, moving to "uncover" when you finish your route is pop warner level),
need to see occasional "bad snaps" based on rating of center/long snapper,
FG blocks need to not magically stick to the guys hand and the game needs to credit your player and the opposing kicker with a block in the right place,
FG trajectory needs fixed,
"gang tackles" "consecutive hits" "finishing hits" and fighting for the fumble all need to happen within the game play,
they need to return to last gen "feel" of control and have the way you hit the buttons matter so you are in control of the "attempted" move,
the ratings all need to matter and make sense (see Ps or Ks on the OL),
kicking game needs fixed (if I up the angle on KOs the ball should be in the air longer - potentially allowing better KO coverage - not just land shorter,
the way the ball moves needs some work,
passing needs more varied ball flight paths,
wind needs to affect the passing game progressively,
blockers should have to "go after" people not be made of some kind of "anti-matter" that creates a black hole effect,
and there is more if you want me to go on...
I don't think that Mocapping 22 people would really work, but they need to get some different hgt, wght players or at least athletes in to mocap, they should mocap them running about 60 yrds - a couple times at full speed, then set up some cones and have them run half speed to cone 1, then accelerate as fast as they can to cone 2, slow down to 3/4 speed from there to cone 3, then sprint through cone 5 & 6 and when you get even with six have them "pretend" they are 5 yards from end zone and "coast" to final line.
They need to have "yard markers" on the field for the mocap equipment so they can have different strides for different hgt players. And they need to get some OL and DL guys in that are different hgts and wghts to do a full contact, but even one on one or one on two drills. It needs so much work!!!
