You can choose to hold RT while selecting the formation, and that Mut 25 coins would be the one you start out of, but it will shift once you are on the line. You could also be audible in the formation you are in, however you can select "on the move" audibles which would be specific to that particular play. For replacing hot routes instead of drawing the play out on the line as the current system, CM Hooe wants to connect the play to offensive systems:
Include offensive system language to the game. There are advantages and drawbacks for each system. Each system has advantages as well as disadvantages. For instance, an Erhardt Perkins offensive scheme could require very high percentage of AWR players across the board in order to play however a quarterback within this system would be given the ability to choose any routes he'd like on the field by using simple phrases.
This is exactly what Tom Brady did in New England for the past two years. The Pro Reads Zone ability could be later adjusted to automatically select the beater route in any coverage strategy defenses decides to call instead of simply highlight the receiver with the most open. In my opinion, altering the Hot Routes system can be complicated due to a number of reasons, however I do believe CM Hooe is onto something with this for at the very least franchise mode.
Of course, there's more to do to make QBs appear like real QBs, not the game. They must look and sound exactly like their counterparts in real life, and although this may require NFL buy-in for specific assets, Madden can always use more of the things that user Detroit Tigers mentions below.
I'm convinced that QB differentiation isn't a type of major issue. There are plenty of ratings, abilities and characteristics Madden nfl 25 coins for sale that have enough tangible effects that you can see and feel. They're getting in the right direction, IMO.
