W/O it, progression based on stats with unlimited potential is HIGHLY unrealistic. Stats based/unlimited potential is very ARCADY, not realistic.
It's essential, if we want realism. Everybody has a potential max. Everyone having unlimited potential is highly unrealistic.
There are Arian Foster's in the game. They are the lower rated players with high potential. These are your Arian Fosters. W/O a potential cap, EVERYONE in the league IS AN ARIAN FOSTER.
Being able to take any 60 rated player and turn him into a superstar is by definition unrealistic.
Because it's not a flaw if we want realism. Tony Romo, Miles Austin, Matt Shaub, Arian Foster all have a potential in real life. There potential is fairly high, but none of them have unlimited potential. The game, having limited potential for every player does provide for all these examples to happen. In the game, there are high round (4-5-6-7) draft picks and undrafted free agents with A potential. These are your Romo's, Austin's, Shaub's and Foster's. What you are looking for, with your examples, is for the game to completely MIMIC what happens in real life. The game, with a capped potential, will do progression from year to year. What you are looking for is the game to re-evaluate a player based on there real life stats. The only way you will get that is with Roster Updates. Unlimited potential, with a stats based progression will not guarantee that player A in Madden will get the same kind of progression that he will get in real life next year.
I could go with an option. If you want an unrealistic, arcady, stats based progression then that's what you want. Just, please, don't muck up my realism for your arcady. And it's not hindering the quality of the game, limited potential is enhancing the quality of the game. It's needs to be greatly expanded to be much more realistic. Actual potential, actual ratings (both overall and individual) should be hidden, and we should only see perceived potential, and ratings. The perceived ratings should only be as accurate as how well your GM, Coaching Staff and Scouts are at evaluating players. The perceived numbers should get more accurate the longer the player is in the NFL and on your team. Progression should be based on things like players ability to learn, players work ethic, coaching staffs ability to teach, team mentors at the players position, playing time, the players potential, etc. But most definitely, it SHOULD NOT BE BASED ON STATS.
Realistic Capped Potential and Progression should be enhanced, not scrapped.
