Exactly it's all based on telemetry and they are wanting to eventually be able to use Madden as a teaching aid for learning how to play football. That is something John Madden always envisioned for this game to become.
The tackling cone is all about the telemetry and teaching people about spatial distance and when to and when not to attempt a tackle, how to properly position yourself to make a tackle. No other game has tried to teach people how football really works based on real fundamentals so I don't see the problem here.
