I want to say most of this stuff isn't my own thoughts i am stealing most of it from the old head coach games and NBA2K16. So I will make a lot of comparison to NBA2K16 upcoming offseason. Also keep in mind that not everyone is hardcore sim players like us as EA also has to cater toward the casual fans.
In game
Fix & update supersim
This has been broke for a really long time as far as stats and time goes and even if that was fixed it needs to be updated on. A lot of people might want to skip the special teams stuff as they are automatic. But in the past it was to much of a risk to miss the kick. I know NBA is different then NFL and to play every game you have to have a supersim but still madden could benefit from it. We should have a supersim that is so detailed it makes it a text game and allows you to just be the coach as lots of people dont have good stick skills. You should be able to call plays, make subs, set strategy etc. Put a speed on it as some people will want to sim through it very fast. Then if its a close game late in the 4th quarter then allow us to easily jump into the game.
Formation Subs
Game Ticker during CFM games
Another feature that has been around in many games and in 2K its in every screen you go to not just in game. This needs to include all news, stats, injuries, standings etc. How often do you check the stats of CPU games? This way you could and it needs to be able to customize what it shows.
In game highlights of games/scores around the league
NCAA had something similar to where they would show boxscores of major games around the country. That needs to be brought back and go one step farther and add video highlights to it
45 man active roster
It was in head coach
I should be able to play a CPU vs CPU game in CFM
Maybe its to ruin the team so you get a playoff spot or maybe its just to play with a star player whatever the reason it should be able to easily be in the game.
Draft
Have private works for prospects
I dont have the exact number but if you follow the draft close in real life you know about how teams bring some players in for private workouts. Think of how cool it would be if you have the #1 pick in the draft and be able to bring in both top QB's in for a private workout and be able to control them. You would use the skill trainers that are already in the game.
In depth breakdown of the tdp 10
If you watch ESPN all they do is talk about the top 5 or 10 players in the draft so those players should have more in depth presention to them
Have the commish announce the draft picks for the 1st round
CFM
Weekly recap/highlight shows
This has long been a request since the days of the last college basketball game.
Players should hold out for more $
Asst coaches / Coaching Carousel
The ability to have a OC & DC is a must and make them matter say if his strength is QB's then all of QB should get a boost. Other teams need to be able to hire them away and you hire there coaches away. Some coaches need to want to become a head coach and others are happy becoming a asst coach forever. If you have a asst coach locked up for a few years and decline the chance for another team to interview him and he should effect you somehow.
Former players should become coaches
In the 2K the blog talked about how Ray Allen started off as a celtics asst coach and then a few years was the GM of the team. How could would it be to have Peyton Manning be the coach of your team?
Team relocation
Another feature that 2K put a lot of time into and at first glance I wasn't impressed but it sounds really cool. It is in madden now but it could be approved on. I don't really know what to say here and im running out of time but basically just read whats in NBA 2K16 and try to match it. A lot of people would want to move a team to LA or Houston.
Practice squad
Give us a list of the highest selling jerseys in the news section
Retire players # for your team
Betting on games
In the real NFL betting on games is the main reason why alot of people watch the games. Have some kind of VC points and let you bet on the spread of the games
Teams need a strategy / team building
This blew my mind when I read it on NBA 2K16 how teams now have 4 states on where the roster are and its rebuilding, selling, contending, buying. This changes the way they make trades, draft and sign FA and they plan for the future instead of just the now. The CPU knows where they stand a rebuilding team shouldn't accept a trade for a over 30 LB just bc the overall are the same. Also the CPU will put people on the untouchable list.
Misc
Add a myleague mode
If you haven't seen the 2K mod e basically it allows you to customize everything in this mode from rosters, games, schedule, cap, ratings etc. every aspect of your franchise needs to be able to customize and changed.
Create a team/ rebranding / building a new stadium
I combined these as they are close to the same thing. Think back to NCAA 14 and before the game came out they were thousands of teams ready to be used on launch from classic teams to super hero teams. Maybe its year 5 and you want to slightly chance the uniforms of your fav team. If I want to change the packers uniforms to pink and yellow polka dots I should be able to. Also you should be able to change the field anyway you want. Then upload pic and be able to use on your field and new logo.
Face scan from a picture with your phone
in the new wwe 2k game they added a feature where you can face scan from a photo. Not everyone in the NFL is able to do a face scan so this would allow you to be able to do that. Also it would allow you to scan your own/face face for generated rookies.
More then 1 injury at a time
Add classic teams
